TMS320F28388S: TMS320F28388SPTPS - SCI Boot Loader Problem

Swati Gangopadhyay

I am facing an issue in loading the kernel file and application file using SCI boot mode in the target hardware using serial_flash_programmer utility. GPIO72 and GPIO84 are set to logic level 0 and 1 respectively. GPIO29 and GPIO 28 are used as SCITX and SCIRX. Following is the screenshot attached for the same. Can anyone suggest what might be the issue?

Thanks,

Swati

Hi Swati,

I was able to get SCI boot mode to work on the F28388D device. For the F28388S, do you have the switch with JTAG set to off and UART on, or what does your setup look like?

Thanks,

Charles

Hi Charles,

In my case the hardware that I am using is custom hardware. So I am using GPIO28 and 29 for SCIRX and SCITX and setting the boot mode pins. There is no switch for JTAG or UART.

Thanks,
