TMS320F28377S: Flash RTOS sys/bios program through SCI

Thepnimit Suparlert

I would like to flash RTOS sys/bios program through SCI, do you have any suggestions about the solution or step to do this work ? becuase I have tried to flash by using "non sys/bios" according to the following steps

1. Use program "Texas Instruments C2000 Serial Flash Programmer Example Package"

2. Use command "hex2000 -boot -a -sci8 <.out filename> -o <output filename>"

3. Send <output filename> through SCI

It's working with non sys/bios just fine but it's not working with sys/bios.

Best regards,

In what way is it failing? Is the program being loaded but failing to run or is the issue happening sooner?

Can you check that the hex file contains the correct entry point?

1. It doesn't have the problem during flash process through sci but after finish flashed the program sys/bios is not start / not working.

2. If I change the program to non sys/bios the program is working fine from flash through sci

3. If I connect with JTAG and press "Flash" or "Debug" in CCS the program is working fine both.

How could I check the entry point of Hex file ?

SCI port C2000 connect with UART linux baudrate 9600

You can open the hex file in a text editor and look at its contents. The hex utility chapter of the Assembly Language Tools guide describes how the entry point is determined and where it is located in the hex file itself.

Also, try following the steps in this post where I describe how to debug an application that has booted standalone from flash. It gives you the steps on how to allow CCS to connect to the device without disrupting its execution so you can see where it got stuck.
