IWRL6432BOOST: Flash custom board using Uniflash

Part Number: IWRL6432BOOST
Other Parts Discussed in Thread: UNIFLASH

Hello, 

My team made a custom board based on IWRL6432BOOST.

It is connected with PC using XDS110 debugger.

Debug in CCS works.

But Flash in Uniflash failed.

COM PORT is recognized. And nothing uses it.

Please let me know what did I missed.

Best regards,

JIYEON.

    Hi JIYEON, 

    That error message from Uniflash usually means the COM port number is incorrect or the com port is already opened by another application. Please confirm there are no other programs running on the PC which are holding that com port open (serial terminal software, GUI, etc...). Keep in mind that sometimes when a program using the COM port is closed, it's possible that the com port was not released properly. You can try disconnecting and reconnecting the USB connection to the PC and also try restarting the PC. 

    Best Regards,

    Josh

    Hi Josh,

    The error occurred because one of the aux pins, UART, was not connected properly.

    Thanks for your support.
