Part Number:AM5728

Tool/software: Linux

Our customer plan to use PCIe+EDMA on their product.

But we don't know how to enable  PCIe+EDMA on am5728.

Now our SDK version is 03.01.00.06

Thank you in advance.

LM317A: LM317A_LM317 current limit difference

Part Number:LM317A

Hello

My customer intend to use LM317A, but we have question.

The current limit in the LM317 data sheet is (VIN-VOUT)  smaller than  40V,

The current limit in the LM317A data sheet is (VIN-VOUT) equal to  40V.

I think  LM317 data sheet is correct (  15V < VIN-VOUT smaller than :0.4V typ  should be correct.

(Its description in LM317A is TYPO) 

Is my understanding correct ?

Best Regards

CC3200: Chinese SSID

Part Number:CC3200

Hi Team,

My customer use CC3200 with AIRKISS,now he is facing the following problem:

1.Chinese SSID can not be recognized,and the reason is router uses GBK encoding for SSID, but AIRKISS uses UTF8 encoding instead, which causes the mismatching. My customer tried to conver GBK to UTF via C language,and it takes about 20kb flash, which is too large for his applicaiton.Is there any other mothod to achieve this?

2.Some router can't receive UDP packets when using AIRKISS.

RTOS/AM5746: PCIe configuration registers

Part Number:AM5746

Tool/software: TI-RTOS

Hi.
My customers have questions on PCIe configuration registers.

Question 1:
About the following registers.
・PCIECTRL_EP_DBICS_PM_CAP [26] D2_SP
・PCIECTRL_EP_DBICS_PM_CAP [25] D1_SP
They looked at Figure 24-163. Do you agree with the following recognition?
Bit = 0 ::: It isn't possible to make state transition in D-state
Bit = 1 ::: It is possible to make state transition in D-state

Question 2:
What is the settings for the following register?
・PCIECTRL_PL_PHY_CTRL_R [31: 0] PHY_CTRL

Question 3:
What happens when you enable the following register?
We can't understand even if I looked at the register Description of TRM.
・PCIECTRL_PL_IATU_REG_CTRL_2[29]INVERT_MODE
Discription:Redefine match criteria as outside the defined range (instead of inside)

Regards,
Rei

Hii,

I am using TM4C1294NCPDT part number and Code Composer Studio.. My Launchpad is acting as Master and as well as Slave also..

Master pin configuration is:

PA2 -------------- SSI0CLK

 PA3 ----------- SSI0FSS

 PA4 ------------ SSI0XDAT0          // MOSI

 PA5 ------------- SSI0XDAT1        // MISO

 Slave pin configuration is:

PD3 -------------- SSI0CLK

 PD2 ----------- SSI0FSS

 PD1 ------------ SSI0XDAT0          // MOSI

 PD0 ------------- SSI0XDAT1        // MISO

I am not able to observe the data in UART console but in console it is showing  "FAILED"....

Kindly go through the below code.. Is there any new things to add..

CCS/CC2640R2F: The wathdog timeout happens much longer (~120secs) than actual programmed 5 secs value

Part Number:CC2640R2F

Tool/software: Code Composer Studio

We enabled watchdog with 5 secs. At the very first time of flashing the code via JTAG cable is connected, the watchdog timeout happens at 5 secs.

During the time-out RESET happens and JTAG communication with CCS is disabled.

When we remove JTAG and re-start the board with newly flashed binary, the watchdog timeout happens at every 120 secs instead of 5 secs.

What could be reason behind getting 120 secs timeout instead of 5 secs?.   

here, is my watchdog code implementation


and below is the WATCHDOG calback function

Hi team,

According to below figure, input data is fixed by processor and we can select which Mipi module we use. but our customer wants to realize that input data is selectable and output data is fixed. It is like opposite way. Is it impossible to use such a way? if impossible, do you have any other recommendation devices?

Thanks,

CCS/LAUNCHXL-CC1352R1: OUT of box test with AWR1642 and two pieces of CC1352R1 launch pad.

Part Number:LAUNCHXL-CC1352R1

Tool/software: Code Composer Studio

We have HW environment(AWR1642 , 2 pieces of CC1352R1 LAUNCH PAD[HW rev B, FW:SDK 2.40.1852] ).

we use SDK(simplelink_cc13x2_26x2_sdk_2_40_00_81).

Our goal is people counting sensor information to CC1352R1 sensor node and to collector node. And just packet dump through USB in each node(1642, sensor, collector) 

in document TIDUED6(http://www.ti.com/lit/ug/tidued6a/tidued6a.pdf), it recommends us to use simplelink_cc13x2_sdk_2_10_00_48.

Which version should we use with our HW setup? It looks like the latest version simplelink_cc13x2_26x2_sdk_2_40_00_81

If we use simplelink_cc13x2_sdk_2_10_00_48 with CC1352R1 LAUNCH PAD[HW rev B, FW:SDK 2.40.1852] , it does not work.

if we use SDK(simplelink_cc13x2_26x2_sdk_2_40_00_81) with  CC1352R1 LAUNCH PAD[HW rev B, FW:SDK 2.40.1852] , it works.

But, it misses patch files for supporting 1642 : 0001-mmwave-cc1352-collector.patch, 0001-mmwave-cc1352-sensor.patch downloaded from 

Actually when we opened it, it is patch file for IWR6843, not IWR1642 (AWR1642).

Here, we can not proceed testing it "out of box" test with our HW environment

This patch contents looks like "triggering sensor to start sensing". We don't know how to create patch for triggering sensor now.

3.1.2.4 Building the Firmware
The firmware for this TI design is based on the collector and sensor example code provided with the TI
15.4 stack. Patches are included with this TI design to apply the necessary changes to the example code.
Follow these steps to apply the patches and build the example code.
1. Download Simplelink-cc13x2-sdk (version 2.10.00.48) from www.ti.com/.../SIMPLELINKCC13X2-
SDK.
2. Project > Import CCS project.
3. Search in C:\ti\simplelink_cc13x2_sdk_2_10_00_48\examples\rtos\CC1352R1_LAUNCHXL\ti154stack
directory.
4. Import two projects: collector_cc1352r1lp and sensor_cc1352r1lp.
5. Apply the patch for collector node:
a. Right-click collector_cc1352r1lp and go to Team > Apply patch…
b. Apply the collector patch (patch is found in Software Files)
c. Right-click collector_cc1352r1lp and go to Properties
d. In Include Options, add folder ${PROJECT_ROOT}/Application/collector_new
e. In Predefined Symbols, add MMWAVE_SENSOR
6. Apply patch for sensor node:
a. Right-click sensor_cc1352r1lp and go to Team > Apply patch…
b. Apply the sensor patch (patch is found in Software Files)
c. Right-click sensor_cc1352r1lp and go to Properties
d. In Include Options, add folder ${PROJECT_ROOT}/Application/sensor_new
e. In Predefined Symbols, add MMWAVE_SENSOR

DS90UB913A-Q1: serializer delay

Part Number:DS90UB913A-Q1

In table 7.10 the serializer delay is defined as 38T or 13T depending on the mode of the chip. The only definition found of T is in table 7.6 as the period of PCLK. If the delay is 38 or 13 times the PCLK then this contradicts figure 10.  Can you confirm that the T used in table 7.10 is the clock of the serial FDP link ?

Part Number:DS90UB941AS-Q1

Tool/software: Linux

my board is imx8qxp,data pata:mipi dsi --> ssd2858-->941-->948-->lcd(1920x720);

in boot up, the gpio3 on 948 sometimes is pull down to 0V while the input GPIO3 to 941 is always 3.3V;

but after there are contents on screen (means display is on,) the gpio3 on 948 is normal to 3.3V;

so,when no dislapy contents input to 941,the 941-948 can transport by GPIO3 independently? ?

Part Number:TPS73601-EP

Dear Sir or Madam

The TPS73601MDCQREP  at our board is always outputting about 4V, when I measure the pin4(FB), it's about 1.6V .

here is my schematic, Are there anything wrong in my schematic ？I've also tried to changed to feed back resistors to different match groups. But It doesn't work .

Additionally , There are two places where I can see the formula  for calculating the output voltage in the datasheet  www.ti.com/.../tps73601-ep.pdf

. 

But which one is the wright one ?

best regards.
