CCS/TMS320F28377D: TMS320F28377D SCI BOOT

Dear TI engineer，

Usually I upgrade the 28377D by Config GPIO72：0/GPIO84:1 and let 28377D enter the sci boot，and use the default GPIO84/GPIO85 as upgrade IO. But now the GPIO85 is used for MDRA, I have to change the GPIO84/GPIO85 to GPIO28/GPIO29. So I want to know what shall I do that I still can upgrade the 28377D by Config GPIO72：0/GPIO84:1?

Please see the F28379D TRM, chapter 4.5 on page 606 which give instructions on how to change the default boot pins to any other GPIO. This should let you move the boot pins away from the SCI pin on GPIO84/85.

Best,
Matthew
