AWR2944EVM: RS232 Connectivity Issue - AWR2944EVM + DCA1000EVM

Hi Deepan,

Can you check with the baud rate as 921600.

Shruti

I have tried it, didn't work either.

Hi Deepan,

Can you check the connectivity with any other 2944 EVM if you have any.

Regards,

Shruti

There is no spare unit available. I have tried it with different PCs as well, same issue. 

Hi Deepan,

Can you check with all the com ports once with the baud rate as 921600.

Regards,

Shruti

I have tried the baud rates of 115200 and 921600 for all the FTDI ports from the displayed ports in the attached image. It didn't help.

Deepan - 

Shruti has moved this post over to my team - I have assigned it to one of my hardware experts - sorry for the delay.

Hello,

Can you please confirm you also have the 12V supply connected? Can you share an image of which LEDs are illuminated on your board?

Regards,

Adrian 

Sorry for the delayed response, the snap of the Board setup post 12V power up - AWR2944 EVM and 5V power up - DCA1000EVM. 

Hello,

It looks like FTDI_NSUP LED is not on. This indicates that the FTDI chip is not receiving the 3.3V supply from the USB. Is your USB outputting 5V as expected?

Can you please try measuring the two below nodes with a DMM and see if you can measure 5V and 3.3V respectively?

Regards,

Adrian

Thank you for your quick response Adrian, I am able to measure 5V and 3.3V as expected, also the LED (FTDI_NSUP) is illuminated (Refer to the attached image). Sorry, the USB wasn't plugged-in for the previous response.

Hello,

Ok, it does not look like there is anything obviously wrong.

Can you confirm the markings on top of the AWR chip?

Can you also probe the AWR 40 MHz crystal and confirm if it is running?

Regards,

Adrian 

Hi Adrian, 
The 40MHz crystal is functional (Refer attached images - (1) Probed at Y3  ; (2) 40MHz XTAL output waveform)


I don't follow, markings as in ?

Deepan

Hello,

By markings I meant the package markings on top of the AWR device, but I can already see them in your latest photo. I wanted to confirm that this is a GP device and not a secure device.

To be honest, I cannot see anything wrong in your setup.

Are you able to run the OOB demo successfully? If so, this would maybe indicate that the issue is with the FTDI chip on the board.

Adrian

Are the SOP jumpers set correctly to SOP2 mode? After the SOP jumpers have been placed, have you reset the device using the nReset button?

Vivek Dham The SOP jumpers should not matter, the SOP mode will get set by the FTDI when the ar1.SOPControl(2) is called.

Adrian 

aozer, from the mmWavestudio snapshot above the DCA1000 is selected. This prevents the SOP setting from the studio. if the SOP setting is to be done from the studio, the TSW1400 needs to be selected and then SOP Mode2 needs to be set.

Hello Deepan,

Were you able to try out the above suggestion?

vivek

Hi Vivek,

I have attempted to change the SOP mode as suggested however mmwave studio said that the SOP mode has been set via the jumpers, we are able to set the mode to SOP2 via the jumper so how can we proceed further ?
