Tool/software: Code Composer Studio

Hi All,

I am working on firmware update through SCI Boot load mode by using C2prog tool, the basic Serial communication(UART)

is working fine when trying to communicate MCU over GPIO84 (TX) and GPIO85 (RX),but unable to upload .hex file to the controller .

1) We configured both GPIO 84 and 85 pins for SCI Port.Serial communication is working .

2) Loading hex file form c2prog (See load hex screen shot),after loading .

3) For Sci boot , We made GPIO Pin as 72 LOW,

4) We have a pull up on GPIO 84 pin and GPIO72 pins.

5) After resetting the controller the Response is (see Boot_2 screen shot).

6) Do we need to give any security key for sci Boot load.

7) I followed TI SPRABV4 application note and used TI Serial Flash Programmer tool to test Sci boot load application as but no success.

Please suggest the standard procedure for uploading .hex file into flash through SCI mode.

Thanks&Regards

Hello

Was the serial flash programmer able to work? That app note should provide all the details needed.

If you have questions about c2prog, please contact Codeskin.

Best regards
Chris

HI Chris,

Thank you for reply, there was a problem in serial port isolation circuitry . I have contacted code skin and shared the details . Now without isolation boot loader mode works.

Thanks & Regards
Naveen
