using ROM_FlashErase in application mode hangs

Other Parts Discussed in Thread: TM4C1294NCPDT

My config: TM4C1294NCPDT eval kit ver. A1, CCS v6.0, TI-RTOS 2.0.1.23, SysBios 6.40.01.15, Compiler TI v5.1.5

Both bootloader and application run @ 120Mhz.

I have a flash bootloader (@ 0x0000.0000) that automatically kicks me into my application in flash (@ 0x0004.0000) on boot up. When I try to erase a section in flash (@ 0x000F.C000), after jumping into the application, it hangs. Are there any known issues with ROM Flash Erase? I am able to erase/program to this address while I am in the bootloader, so weird part is why in the application it seems to hang?

Any ideas?

Thank You!

Hello Hiowatha,

Instead of using the ROM based flash erase, can you map the erase function to the Flash itself and let us know if it hangs?

FYI: I haven't been able to reproduce this in a couple of days. I am now thinking I must have been doing something wrong. I will keep an eye on this a bit longer, otherwise, I assume things are actually working as intended.

Hello Hiowatha,

I agree. Let us keep a look out for any such anomaly. It would be good to understand why it is occuring.
