Part Number: AWR1843
Other Parts Discussed in Thread: UNIFLASH,

Hi,

I received the AWR1843 circuit board that I designed, but I can't burn it with uniflash.

Prompt that the serial port cannot be opened.

Please give me some advice.

Thanks

Can you please provide us more information about your custom board?

Is it identical to the BOOST EVM?

thank you

Hello,

Do you have the device in the correct SOP mode?

Did you toggle the NRST after powering up the device to make sure that the SOP mode was latched correctly?

Regards,

Adrian

Hi Cesar,

This board is identical to the EVM board. Use an external XDS110.

Thanks

Hi Adrian,

I tried the method you mentioned, and the SOP is correct, but it still doesn't work.

Thanks

Hi Adrian,

add more information.

The serial number of XDS 110 is 0000000, is it ok?

The tesetboard.dat shows TDO FAIL.

Hi Adrian,

I want to know whether this log indicates that the chip was found?

I tested this log with CCS, but it still cannot be downloaded with uniflash.

Hello Yunlong,

Are you trying to flash over JTAG?

Uniflash only supports flashing over the RS232 pins with mmWave devices, so if you are trying to flash over JTAG it will not work.

Adrian

Hi Adrian,

I have solved the flashing problem. I made a mistake when wiring.

Thanks
