Hello Team,
we are trying to implement Flash APIs for f2800137 in our main code, which was checked previously through example present in C2000Ware and works fine.
but when we used flash APIs with our main code, the code is stuck in "while loop" present in "f280013x_sysctrl.c" file.
following is the function, and highlighted part is the loop where code stuck :
Please, help us to solve this issue.
your efforts highly appreciated from this side.
Hi Nilesh,
Can you attach the linker command file and map file?
Thanks and regards,

Hi Yash,
For debug, instead of using FLASH_BANK0_SEC_16_23 and RAMLS0 for flash API, can you use a different Flash and RAM range that is not used by other sections like .text and .bss etc.?
In your application, I think the flash API is not executed yet before the PollX1Counter(). Correct?
Are you successfully able to execute the flash API usage example provided in C2000Ware?
Thanks and regards,
Vamsi
Hi Vamsi,
As suggested for use different flash and RAM range, i was checked with FLASH_BANK0_SEC_96_99 (0x98000 to 0x99000) and RAMLS1 . But no changes observed, again stuck in same loop.
yes, the flash API is not executed yet before the PollX1Counter().
yes, successfully able to execute the flash API usage example provided in C2000Ware.
Thanks and regards,
Yash
Hello Yash,
If the code gets stuck in the while loop you are pointing then it means that your crystal hasn't started or crystal is bad.
If the crystal is configured properly before PollX1Counter() while loop and its oscillating the counter should saturate and get you out of the loop and let you proceed.
Also when you get stuck please look at the register view and let me know what the counter value shows. Like shown below in registers view window
Mine shows 7FF which is expected for normal operating XTAL
Have you tried the same on multiple units ? Also Are you using launchpad ?
Thanks!
