IWR6843: Few of our IWR6843 RF board failed to boot and stuck at SOC_waitBSSPowerUp() ...

Part Number: IWR6843

Hi,

Few of our board failed to boot the demo application in mmwave_sdk_03_02_00_04 SDK. When traced all the calls the below are the details.

Below are the calls succeeded in our trace and finally stuck at SOC_waitBSSPowerUp()

MmwDemo_edmaInit
MmwDemo_edmaOpen
MmwDemo_hwaInit
MmwDemo_hwaOpen
MMWave_init
MMWave_initLink
MMWave_initCRC
MMWave_initMMWaveLink
MMWave_deviceGetDeviceInfo
rlDevicePowerOn
SOC_waitBSSPowerUp

When the BSS power up failed what would be the reason? and what should be checked in HW circuit? The same image works fine in other boards. We want to diagnose the HW issue so we need the area to focus for our investigation. Could anyone help?

Regards,

Senthil
