DCA1000EVM: DCA1000EVM + IWR6843ISK Resp Timeout Error

Part Number: DCA1000EVM
Other Parts Discussed in Thread: IWR6843ISK, UNIFLASH

Hello everyone,

I am currently trying to acquire sensor raw data with a DCA1000EVM and an IWR6843ISK EVM. I did this prior. but at the moment it is not working. I have switched to a new PC and am at a loss what to do.

All configuration runs without error, but when i press DCA1000ARM and try to trigger a frame, i get a Response timeout. Does anyone see an obvious problem?

Hello

The "No LVDS Data" error can be caused by multiple different issues, but the reason is almost always DCA1000 related rather than mmWave Sensor related. You can try reflashing the FPGA on the DCA1000, make sure there is no SD card inserted into the DCA1000, make sure four DevPack COM ports show up in Device Manager which signify the DCA1000, and you should also look through E2E as many others have had the same problem with different solutions.

Hi Pedrhom, as i am an avid reader of the forums and had various problems over my time with the DCA1000, I have scrolled many posts in this and chinese forum. The issue is, that when triggering a frame, i get a response timeout. I havent found this problem somewhere else jet and it just occurred to me recently. Flashing the fpga may help, but i have two DCA boards which were working and suddenly this stopped.

Hello,

If both DCA boards stopped working in the same exact way then I would potentially check the mmWave Sensor's capabilities. For example try running out of box demo or something along those lines to confirm the sensor can start properly. But first, I would try erasing the firmware on the sensor right via Uniflash and trying mmWaveStudio again. If that does not work then try flashing a compiled binary such as OOB and running that demo

I have also tried three different IWR chips, one with a custom board, one ODS type and one ISK type. the behaviour is always the same. I have tried flashing the Demo on all these board with UniFlash and that works fine. The only thread i find with similar behavious is this one https://threads489.rssing.com/chan-6462796/all_p12462.html and this one https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1013895/iwr6843-resp-timeout-using-iwr6843-and-dca1000evm which suggests having a power supply issue, but i checked again and my power supply has a 5V on 4A rating.

Is the IWR sensor powered over the DCA1000 boards power supply or the PC USB connection. I attached a 2m USB extension cable, is it possible that the voltage drop is too much when triggering the board?

Well my idea fixed the problem. The USB cable was too long or the USB port didnt have enough power to power the IWR chip. Could you please add that in the debugging manual? Currently it only suggests that the Power supply of the DCA board is too weak and doesnt suggest that the IWR board is still powered over its own USB cable. Is there a way to change this?
