DCA1000EVM: DCA1000 becomes unresponsive after 4.5 hours of power on

Hello,

Thank you for reaching out to Texas Instruments. A team member will assist you with your query soon.

Thanks,

Hi,

     I am not aware of any such behaviour and have not encountered it till date. I woudl suggest you can try to have ar1.CaptureCardConfig_ResetFPGA API being used in your scripts of capture to ensure proper state of DCA.

regards 

Hi,

Thanks for your reply.
I think that the ar1.CaptureCardConfig_ResetFPGA API is a mmwaveStudio feature.
In CLI Tool.exe, I try to run it with the following code.

int dca_config(void)
{
～～～～
/* Reset the FPGA, to avoid any errors for last execution */
s32CliStatus = ResetRFDCCard_FPGA();

regards 

OK if does the same work.

Regards

I tried it.

(1) Fixing mmwave_studio_cli.exe
Fixed the following in mmw_main.c

		/* to Stop DCA1000 capture */
		else if (_stricmp(inputCmd, "dcaStop") == 0)
		{
			gCliCmdRcd = CLI_CMD_DCA_STOP;
			if (rlDevGlobalCfgArgs.gModuleExecState.dcaCaptureState == DCA_CAPTURE_TRIG)
			{
				/* stop the DCA1000 Recording */
				dcaStopRecording();
				dcaCaptureDoneEvent = 1;
				rlDevGlobalCfgArgs.gModuleExecState.dcaCaptureState = DCA_CAPTURE_STOP;
			}
			else
			{
				printf("[WARNING] DCA1000 is not yet triggered\n");
			}
			dca_config();   /* Add (ResetRFDCCard_FPGA()) */

(2) Start mmwave_studio_cli.exe (start of millimeter wave measurement)

(3) 2 hours later
Execute dcastop
Execute deviceRestart
# deviceRestart is implemented as follows (to measure without rebooting, the command to Soft Reselect IWR6843)
e2e.ti.com/.../iwr6843-how-can-i-take-data-multiple-times-with-mmwavestudio-cli-tool

(4) Start mmwave_studio_cli.exe (start of millimeter wave measurement)

(5) 2.5 hours later
Ethernet stop
After that, communication with DCA1000 was impossible.

I also tried the following for additional information.

www.ti.com/.../spruij4a.pdf
Table 9. Push Button Functionality Information

After 4.5 hours, when the DCA1000 was unresponsive, pushing this switch had no effect.

In both cases, turning off/on the DCA1000's Power Selection Switch caused the DCA1000 to operate normally.

Table 9. Push Button Functionality Information

After 4.5 hours, when the DCA1000 was unresponsive, pushing this switch had no effect.

The above refers to SW7 FPGA_RST.

Hi,

          Can you please try to reflash the DCA FPGA firmware(follow instructions in user guide section 9 - https://www.ti.com/lit/ug/spruij4a/spruij4a.pdf) with this image and try? 

Regards

Hi,

I don't think it makes sense to reflash the FPGA Firmware.
I have 8 DCA1000s and they all work fine except for the 4.5 hour problem.
Another department in my company also has the 4.5 hour problem as well.

I assume it is a DCA1000 issue as there are several similar questions on E2E Support.

Regards

Hi,

            Can you confirm the firmware version on all the hardware(s)? This can be read from mmWave studio when you connect to the DCA1000, FPGA is an integral part of DCA and hence I am advising to flash the shared firmware.

Regards

Hi,

Firmware is "DCA1000_FPGA_RECORD_V2.8_05JUL2019.bit" for all units.

This is the latest as of 2019.
software-dl.ti.com/.../mmwave_studio_manifest.html

The following URLs are drafted after 2020 and are expected to be similar Firmware.

Hi,

          Thanks for confirming on the firmware version. I am aware about these threads, and therefor are suggesting you to flash the older firmware and confirm the repeatability of issue.

Regards

Hi,

I will try to reflash with firmware older than "DCA1000_FPGA_RECORD_V2.8_05JUL2019.bit" and see if it works.

Where can I download the older firmware?
I couldn't find it below.

Hi

Thanks. I have shared it in my previous replies.

Regards

Hi,

Thank you very much.
I'll try v2.7!

Regards

Sure.

Regards

Hi,

The problem has resolved in V2.7.
I have performed the following checks.

What is the difference between V2.7 and V2.8?
I looked for Release note but could not find it.
Is it possible to resolve this issue as V2.9?

Regards

Hi,

         Yes we are working on fixing the observation. Thanks for the confirmation.

Regards

Hi,

Thanks for considering the fixing.
I would like a fixed FW by the end of June, can you get it in time?

Regards

Hi,

           Working on it, will keep you posted.
