tusb3210 driver and firmware problem
hi all:
i make a pcb with tusb3210 controller.i want to use this chip to make interface between usb and i2c.this is the first time i used this chip, so there are some problems.
1.my design base on SCH THS8135 EVM FINAL,convert usb to i2c.
the only different of this part between offical sch and mine is that i use a resistent connect PUR and DP.
2. when i plug the pcb to pc, it can be recognized as a usb device with a yellow question mark, i installed the apploder software to pc,then i modified new apploder.inf as USING the apploder driver and moved INF SYS BIN 3 files to the same path. then i tried to update the driver of the usb device, but failed.the pc can not find the file which nessary.the usb device detial is:USB\VID_0451&PID_2136.
3.I install TUSB3210 EEPROM Programmer,but there is NO TI TUSB3210 EEPROMBURNER shown in the device manager.in another post, i find that "he TUSB3210 device instance must appear in the EEPROM Burner even the error appears in Win7, before run the "TUSBxxxx EEPROM Burner" you must have the "TI TUSB3210 EEPROM Burner" driver correctly installed, please go to “Device manager” and verify you can see the “TI TUSB3210 EEPROM Burner” instance. If you can’t see the instance please install the “TI TUSB3210 EEPROM Burner” driver. "what is the TI TUSB3210 EEPROM Burner" driver? where can i get it?
4. if this problem sloved,where can i get the firmware of the THS8135EVM that i can download to the eeprom directly? i mean the hex or bin file,not the source code.
best regard.

SPI programming
HI,
I bought Tiva C Development kit and tried out SPI programming as explained in the spi_master.c file available in the examples folder.
But for some reason all I receive is 0s from the SSI interface. The spi_master program configures SSI in master mode and sends out three letter "s" "p" and "i" and expects them back but all I receive is 0s.
I have my own board which interfaces a spi flash memory with the SSI interface and there also I see the same problem. I do not see the chip select, the SSI0FSS, pin going low and neither I see any clock on the SSI0CLK pin.
Could someone please throw some light on this?
best regards,

bq78pl116 .aux file generation problems
Hi there guys.
It`s me again, this time is because I get some errors on generating of the .aux file.
So I did the 15th steps in the slua505b, and I have a csv file with the logs needed to generate file.
although all was ok, with the logging and so on, I still have a problem generating aux file.
The parameters I set are as fallows :
6 cell in series
parallel cels is 1
1st discharge current is 5330mA
pack capacity is 11000mA
I am not sure why the logging of the capacity is 5330/10, I am using the 10 times option, but not sure why i am logging current/10.
anyway, I am attaching the file and maybe you can help me.
the chem id is 1148
And please tell me what I was doing wrong.
the csv file is the one generated, no modifications or so.
thank you very much

C2000 micro inverter questions
Folks,
I'm looking over my new solar micro inverter development kit, TMDSSOLARUINVKIT, and have a couple questions.
1. My board is rev 4 but the schematic in controlsuite is rev 1.0. do these match?
2. T2 is listed as VITEC 58PR6962 TFMR Flyback, ViTEC 58PR6962. I called Vitec for datasheet, they said its a custom part and to call TI for datasheet. Who should I call to obtain this?
Thanks,
Craig

New Customer Product Selection
Hi,
My apologies if I am breaking any forum rules, it's my first time posting.
I am interested in a signal processing experimentation platform. I am working on a system that requires a platform that can send out and read in analog signals at 500+kS/s. This system should be able to handle FFTs and other signal processing methods of this nature.
Can you recommend some ti products I can use?

SD card is not mounting in DM37x
Hi All,
We are using custom board with Android GingerBread 2.3.4 with 2.6.37 kernel version.
We are using nand images for booting and SD card is using as general storage device. We are using FAT file sysyem without any partitions.
It is working fine with normal system start-up. After booting completes, If i unmount it through
Settings->stoarge->Unmount sdcard.
After unmount complets, removed the SD card. Again insert and press on mount sd card.
It is not mounting and saying like "Blank SD card".
Is it known issue? Can any one please help me?
Thanks,

TPS7A8101 output voltage can't be adjusted
I just want to use TPS7A8101 LDO to get a output voltage 3.3V. I do the design according to the datasheet. But the problem is that now the output voltage is same as input voltage. Eg, input voltage is 3v, then output voltage is 3v too, Or input voltage is 5V and the output voltage is 5V as well. It looks FB doesn't work. I measure the NR pin, the voltage is fixed at about 0.8V, but the FB pin's voltage is not fixed, it looks changed with the output voltage. But in theory, the FB pin's voltage should be fixed and output voltage should be fixed too if the divider resistors determined.
Can anybody help me on that, I am very confused now.
Thanks in advance.

CC2543 on UART
Hi,
I just bought a CC2543--CC2544 Development Kit recently and would like to send serial data from an Arduino Duo MCU to the CC2543EM for it to send the data wireless over to the receiver.
I've downloaded the sample program in swrc257 and tried using the uart_poll example to send data to the receiver. My question is: in the example in swrc257, does pressing S1 make the transmitter send its allocated uartTxBuffer[] to the uart Tx port? Or does it send uartTxBuffer[] for wireless transmission over the air?
Also, how can I configure/program CC2543 to send data wirelessly from whatever that comes in to its UART Rx port? Or is it by default that whatever data is received at its UART Rx port is automatically sent wirelessly?
Regards,
Marcus

MSP430 Launchpad external 3.3V supply
Hello,
I am attempting to externally supply +3.3V to the MSP-EXP430F5529LP. I have removed the 3V3 jumper (JP2). The 5V jumper (JP1) is in place. During testing, I have noticed that when a USB cord is connected, +1.8V appears on the 3V3 pins before I have attached my external supply. I have other components that will be supplied by the 3.3V. I would like for the 3V3 pins to have either 0 or 3.3V on them, depending on whether the external power supply is switched on or not. This will avoid any unpredictable behavior by the other components. What can be done here?
Thank you,
Will

wl1271 timeout on AP and MR initialization
My platform is a BeagleBone Rev C with a custom cape containing a Murata LBEE5ZSTNC-523 module, using the SDIO interface. The Linux revision is 3.8.13-bone64. The firmware that is being loaded is wl127x-fw-5-sr.bin (Rev 6.3.10.0.133).
Station mode seems to be working great, although I had to use expert mode to calibrate because the auto-calibrate doesn't seem to work, and so I am not 100% sure that I chose the proper parameters.
The problem is AP and MultiRole modes. In both cases the driver gets stuck waiting for chip initialization to complete, e.g. the following messages:
[ 275.435825] wlcore: ERROR timeout waiting for the hardware to complete initialization
[ 275.452881] wlcore: ERROR firmware boot failed despite 3 retries
In the case of MR mode, the wl127x-fw-5-sr.bin firmware is already running because station mode was already initialized on wlan0, and then the driver attempts to reload the firmware with wl127x-fw-5-mr.bin (as it seems it should). But the driver times out waiting for the firmware to complete initialization. I tried increasing (doubling) the timeout period; that didn't help. The ifconfig wlan1 ... up command that was used to initiate the MR initialization ends up locking up the console.
In the case of AP mode, the wl127x-fw-5-sr.bin firmware is loaded initially, and then later in the initialization process, there is maybe a reload of the firmware or an additional firmware is being loaded. In any case the loading process seems to complete, but not the initialization prompt that the driver requires. The hostapd ... command that was used to initiate the AP initialization fails with:
Configuration file: /etc/hostapd.conf
Could not set interface wlan0 flags: Invalid argument
nl80211 driver initialization failed.
rmdir[ctrl_interface]: No such file or directory
I have attached a zipfile containing verbose dmesg logs to this post.
Please let me know if you can give me any clues to solve these issues.
Thanks!

Changing from ADS1298 to ADS1198
Hello,
I have an ADS1298 kit and I developed a board of my own using an MSP430f5529 to communicate with the ads1298 board. Everything worked just fine.
Recently I bought an ADS1198 kit and when I tried to use it with the same MSP430 board, it didn't work. The ADS1198 board is working with the MMB0 board, but not with mine.
When I watched the SPI SOMI with the oscilloscope, I noticed that the board is triggering DRDY, but when the SCLK is sent, nothing comes out of the SPI.
The registers values are set the same way that the LabView software does, the AVDD and DVDD are configured the same way my ADS1298 was and the initialization sequence is also the same I used on my ADS1298.
Any idea what could be wrong?
Thanks,
Gean Chu

TMS320C6418 problems with SDRAM
Customer used old revision of Micron SDRAM (MT48LC16M16A2TG-7E:D 115nm) with TMS320C6418 with follow configuration:
EMIF_GCTL = 0xfff000a0; // EMIF global control register
EMIF_CECTL = 0x00000030; // EMIF CE space control register
EMIF_CESEC = 0x00000002; // EMIF CE space secondary control registers, default value
EMIF_SDRAMCTL = 0x63228000; // EMIF SDRAM control register
EMIF_SDRAMTIMING = 0x00000444; // EMIF SDRAM refresh control register
EMIF_SDRAMEXT = 0x00094D5B; // EMIF SDRAM extension register
But with new revision of Micron (MT48LC16M16A2TG-7E:G 50nm ) They meet problems.
Customer used http://www.ti.com/lit/an/spra433e/spra433e.pdf for configuring EMIF for new memory, but it wasn't successful.
Could you send recommended configuration for interfacing with MT48LC16M16A2TG-7E:G
