Other Parts Discussed in Thread: SYSBIOS, , TEST2

Tool/software: TI-RTOS

Hello,

I've used TMS320F28377D with SYSBIOS, It was working properly utill now ( Flash booting OK by Emulator and Power Off/On)

"Flash booting by power off/on" is not working after adding some variables & tables with intial values as below , however" booting by emulator" is working (started by the emualtot after downloading to flash).

If remved above variables, it wroks. I couldn't resolved this issue at all. Could you please review attached my project & command file & bios.cfg & map files.

Please help me to find the clue.

Koh,

What do you mean by not working?
Did you make sure to set the boot pins for boot to Flash mode?
Do you have any GPIO toggle or other signature that indicates whether the application execution started or not from Flash?
Did you get any warnings/error when you compile the code?

Thanks and regards,
Vamsi

Koh,

Check where the new tables are mapped. If you are mapping them to Flash, try declaring them as const type.

Thanks and regards,

HI Vamsi,

Boot pins for Flash mode is OK, because if not included those variable and table, it works, all task and function are working ( So I see serial output message before BIOS_start().

While all same condition, if included those, it reboot repeatedly ( I can not see serial output message)

Hi Vamsi,

If I changed those variabls and tables with non-initilized values, it works by power off/on.

it seems to releated .cinit .ebss so that there would be miss on CMD file.

I'm attaching map files & BIOS.cfg and CMD file again.

How to debug boot procesure with using SYSBIOS step by step before main() ?

Hi Vamsi,

The issue was resloved, it caused by watchdog.

Now it is working after disable watchdog timer

Thanks for your support.
