Max SPI Flash size for ROM boot code
From the TRM, an SPI boot device restriction is that the ROM code can only handle 24-bit addressable devices. I infer that the maximum flash size is 16M x 8.
Correct?

SD Card with TMDXIDK3359
TI Forum,
I am attempting to make a copy of the supplied SD card for TMDXIDK3359. Following the instructions from SYSBIOS Industrial SDK Getting Started Guide on Running Application from SD card.
Using HP USB Disk Storage Format Tool V2.2.3 (v2.0.6 unavailable) to format the card without complication.
Copied the "MLO" and "app" from the SD Card supplied with the IDK.
When I power on the IDK with the new SD Card, nothing appears on the serial terminal and there is not communication with the TwinCat software.
If I use the supplied SD Card, I get the following on the terminal (and the demo software behaves as expected):
*** StarterWare AM335x Boot Loader. Build - 1.0.0 ***
Copying application image from MMCSD to RAM
Copying to RAM completed successfully
Image Copy Successful, Executing Application..
ECAT Limited Demo - 1.0.14
I have tried multiple SD cards: SanDisk SDHC Card 4GB Class 4 and Kingston SDC4/8GB)
Any advice would be appreciated.

Using xds100v2 from a remote PC
Hello,
as a preliminary note: our company here in Germany is working on a qualification kit for the TI compiler in cooperation with Thomas Suchyta (t-suchyta1@ti.com). To make executables run on an eval-board(connected via xds100v2) we are using the script c:\ti\ccsv5\ccs_base\scripting\examples\loadti\loadti.bat provided by Code Composer.
I have problems to make this eval-board run from a virtual machine (vmware) as the host does not release the xds100v2 device to make it usable for the client. Using of a virtual machine is a customer's requirement so I can't change that.
My question is now: is it there a simple way to make loadti run as a client server application? That means the compiling occurs on the virtual machine and the testrun with target connection is done on a physical machine.
I found some scripts in c:\ti\ccsv5\ccs_base\scripting\examples\loadti\ that sound very promising, but I found no description:
- dsSetup.js
- memXfer.js
- ...
I would expect somthing like that:
1) start debug server on PC1
2) do the compiling on PC2
3) call of loadti something like that:
"${LOADTIPATH}/loadti.bat --remotemachine=PC1 -r -c ${CONFIGFILEPATH}/${CONFIGFILE} $1"
Thanks in advance

Max trace length allowed for 32-bit LPDDR to AM3715
Customer is doing layout for AM3715. They are concerning about the DDR signal routing and max trace length allowed for a 32-bit LPDDR to AM3715, I pointed them to 6.4.2.2 on page 185 in the datasheet, but he said the data is not good enough for them to layout the board. Any help is highly appreciated.

MSP430F6736 Blowing electronic fuse without really trying
MSP430F6736
MSP430 USB Debug Interface FET430UIF
CCS v5
Is it possible to somehow mangle the MSP430F6736 lock bits through errant code?
After a software change, uploaded and running a test, I realized that it had referenced and wrote to an array offset that was 1 greater than its allocation. As in:
unsigned char aArray[15];
aArray[0]=0x00;
...
aArray[15] = 0x01;
Because, since this mistake, all attempts at accessing through 2 wire SPI via the FET430UIF are met with "fuse blown" messages.
Also, using the Elpotronic FET-Pro 430 software which tends to solve connection problems (sets the UIF to the correct 2 wire JTAG mode) also fails.
Reading Code File ........................... done
-- Code size = 0x54CA ( 21706 ) bytes
=====================================
JTAG communication initialization.... failed
Verifying Security Fuse .................... failed
--------------- FAILED !!! -----------------
I restarted the entire workstation, the UIF and the target. No change.
I and also tried a second target and in this case the Elpotronic software connects just fine. I haven't tried this second target with ccs. I'm now worried that I will blow the second board, too, if indeed it's possible to break the security fuse so easily!
Is it possible to correct this by wiping the flash memory of the target? I assume this would clear everything. Can I use the FET430UIF interface for this purpose?

BLE Maximum data rate.
TI CC2540 in our project, but we concern the chip's BLE data transfer rate, by searching internet, looks the data throughput is low, around 2k bytes to 6k bytes, "http://processors.wiki.ti.com/index.php/CC2540_Data_Throughput".
May i know the max data transfer rate for TI CC2540 & TI BLE software stack at application layer?

Micron eMMC and OMAP L138
Hello, we would like to upgrade our OMAP L138 system to use Micron's automotive rated eMMC.
Micron state we need "eMMC 4.41" compatability. The OMAP's data sheet says "MMC V4.0".
Does the OMAP's H/W support eMMC 4.41?

Can INA331 be used in the signal amplification of the microphone electret capsule(with built-in FET)?
Hello,
My application is to amplify the 1mV order mic electret capsule signal of bandwidth 20Hz to 22kHz in a gain of 1000.
The mic and the whole circuit are required to biased by the resistor with a 3V supply voltage, so INA331 is chosen for this application.
Is the attachment circuit correctly use of INA311? Or any modification is required? If I use the configuration given in the attachment, how small the noise value be calculated & evaluated and required using this voltage reference(Vref) IC that I should choose? could you please suggest the voltage reference suitable for this application?
The R in the figure may vary from 1k to 11k depending on the different brand of mic.
Thank you very much in advance for any expertise advices, comments and feedback.

HDMI to LVDS Conversion Options
I was wondering if TI has anything to offer for a HDMI to LVDS solution? I must admit I am not very familiar with the high speed interface lineup, but looking through the parts I did not see anything that would perform this particular function directly, though it looks like it may be possible with unencrypted video with a pair of devices (i.e. DVI receiver coupled to a LVDS transmitter).
In any case I was wondering what the best solution TI has to offer for this would be if there is anything practical, and if this is the proper place to ask, thank you for your help.

wifi reconnect in devkit 2.1 gingerbread
Hi,
I'm using the wl12xx driver and wifi stack in Devkit 2.1 Gingerbread. It works well enough for basic usage.
But there are problems. One major one is handling of reconnecting when the AP goes out of range or other form of loss.
I noticed in the userguide, it says:
http://processors.wiki.ti.com/index.php/TI-Android-GingerBread-2.3.4-DevKit-2.1_UserGuide
Known Issues
After connection drop WiFi doesn't connect to Acess Point
automatically. User need to disconnect and connect again.
Has this issue been fixed since the release and if so, are there
patches available?

PCM3070 programming
Hi,
I am using the eval board and PPS for development. It is working as designed. I use the generated .cfg file see what is sent to the eval board.
When I send that data to our target HW, I hear audio for about 1 second, then nothing.
I captured the I2C EVAL board transactions with an analyzer, and I see much more activity than just the contents of the .cfg file.
Can you please what else PPS is doing to the 3070?
Thanks!

DRV8312 getting hot
Please excuse what is probably a complete newbie question but I'm having another problem with my DRV8312-69M-KIT. I'm trying to run the BDLC_Sensorless project with a small outrunner motor. I'm at build level 5 so its just running at a fixed duty cycle with closed loop commutation (zero crossing bemf). Even at a duty cycle of 0.1 to 0.2 the DRV8312 gets really quite hot. Its only drawing 0.5A to 1.0A from the 14V power supply. It would appear that most of this is being dissipated in the DRV8312 rather than the motor. Any idea what's going on?

TUSB1310A
Hi,
I'm using TUSB1310A with Synopsys xHCI usb host controller on our FPGA (Altera) prototype.
USB2.0 (over ULPI) works without any issue. However I'm getting weird behavior on USB3 IF.
On the first time firmware runs, the phy returns no receiver is detected while on the 2nd time the receiver is detected.
On the waveform, there is an observable difference on rx_elecidle line behavior but I have no idea what is causing this.
Reset de-assertion in failing case:
and then on tx_detrx falling edge:
On success it looks like this:
I use 40MHz XTAL, strapping values are being set by pull registers, RESETN is de-asserted after FPGA isprogrammed which takes more than 1sec, so PS and strapping values should have been stable.
I would appreciate any help...
Thanks

Need Help for Ultrasonic Imaging Applications of LM96570/LM96550/LM96530/AFE5805
Hi, everyone. I recently use a set of TI product for ultrasonic imaging. Here are several problem that I have met. Really Need your help T_T !
Q1: I have already read Mariusz’s post (http://e2e.ti.com/support/other_analog/imaging_afes/f/239/t/230591.aspx) about how to get two or more chips LM96570 synchronous in multichannel application. So I have the same doubt because I need to use four chip with my application.
Q2: There are so many supply voltages for LM96550 to make it work well. How to simplify this supply design? Take my design for example. And please let me know if there is any unreasonable point.
I use a power-supply module to supply +50V and -50V; then use LDO to generate +40V and -40V from +50V and -50V respectively; use LDO to generate +10V and -10V from input power supply +12V and -12V respectively; and input power supply +3.3V.(Power +12V, -12V, +3.3V, is external input power)
Q3: A serious problem, that the power supply pin called VDD/VSS is break through being shorted with GND, is occurred during our firstly use. Why? It confuses me.
The schematic is showed as follow figure 1. The LM96550 is configured “CW” mode, so its output pulse is default 10MHz positive & negative high voltage pulse, as we measured in figure 2. When power on, this pulse is driving the LM96530. And the supply current grows high abnormally. Then we power it down immediately, and find that the power supply pin VDD/VSS have already been break through, shorted with GND.
It doesn’t make sense that the LM96530 is declared to accept the continuous wave up to +/- 60V in datasheet. But do NOT give the maximum acceptable frequency of continuous wave. So I guess that whether the frequency is too high that causes fatal damage to LM96530!!! Anyone can confirm my assumption.
Figure 1.
Figure 2.
Q4: LM96530 can be work well under single trigger. We find a fact that LM96530 can NOT be completely switched off. See figure 3, we input a high voltage pulse (the blue line indicated, almost -50V which is lasting 250ns) which results in some leakage peak (the yellow line indicated) at high voltage pulse edge location.
Figure 3.
Q5: Following Q4, we switch on one channel of LM96530. The output of LM96530 shows as figure 4, with a strong oscillation lasting about 5 us. When we put a 100nF cap between LM96530 output and GND close to LM96530, the result shows in figure 5. The effect is remarkable. So is it recommended to put such a cap at the each output of LM96530? But there is still an echo-like wave at rising edge, witch maybe wrongly regarded as front reflecting wave. Is there a way to eliminate it?
Figure 4.
Figure 5.
Q6: It’s sure that LM96511 is compatible with LM96530. But, if I replace LM96511 with AFE5805, is it still compatible with the output Vpp of LM96530. What’s the maximum analog input signal for AFE5805? In datasheet, it declares input voltage of LNA to be 250mVpp and internal diodes to be 600mVpp.
Thanks for your help !

the frame rate of a decode-only-channel
We are working on DVR RDK v03.50.00.06. We use a customized usecase original from usecases/multich_vdec_vdis.c, pls ref another post: http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/717/p/261372/919800.aspx
We found a strange thing about the "speed" of decode-only case. The speed are under our expectation. Furthermore, lower decode channels sometimes are slower than more ones!! There seems be one invisible limitation. Is there any way to break the invisible limitation and then to reach the "full speed"?
