Hello,

The issue is that the flash kernel is setup to configure GPIO28 as Rx and GPIO29 as Tx by default.

In line 140 of flash_kernel_c28x_dual_ex1_sci_flash_kernel_cpu1.c, please change the sciGetFunction() call to use SCI_BOOT instead of SCI_BOOT_ALT5 for GPIO12 and GPIO13 to be used.

Best,
Matt
