Hi,

I have designed the IWRL1432 custom board and using uniflash to flash image file. i am getting following error. I have connected RS232 _RX/TX port to flash the image

Also i have attached the schematic.6153.mmWave_sensor_brd_1p0.pdf

I have pulled down SOP0 and SOP1 to GND via 10K.

I need your support to solve the issues.

Thanks,

Hi Sankar,

After a quick look at your schematic, it seems that the SOP lines are not brought up and controlled in your design.

To modify the functionality of the device, you need to change the SOP modes by external circuitry. To understand more about the OSP modes and their functionalities, please refer to the device data sheet: https://www.ti.com/lit/ds/symlink/iwrl1432.pdf (section:8.6 Boot Modes)

You can refer to the example schematic for the IWRLL1432BOOST EVM for the SOP circuitry: https://www.ti.com/tool/IWRL1432BOOST

Thanks,

Swarnendu
