IWRL6432AOP: IWRL6432AOP

Hi, 

You need to use the switches on the EVM to set the device into 'Flashing mode' then you can load FW for different applications using Uniflash or the SDK visualizer. You can refer to the xWRL6432 Quickstart Guide section on this page for instructions on how this can be done.

Hi C.C, 

My apologies for the misunderstanding. There are a couple of options for achieving this. 

1. Follow the expected flash programming sequence for flashing mode. This will still require setting the device into flashing mode by controlling the SOP0 pin perhaps using GPIO. Then you will need to send the appropriate bootloader commands and the new image over UART. For more information on this process please refer to the xWRLx432 Bootloader flow document and section 4.5 of the IWRL6432 TRM

2. Utilize the Secondary Bootloader (SBL) to achieve flashing a new image over UART with the device in functional mode. This would require the device to already have the SBL application flashed (and optionally a factory backup image) then upon reset you can decide if you want to flash a new image or boot with the existing image. Please refer to the SBL documentation in the SDK for more information.

Best regards,

Josh
