AM2634: Flash block/sector erase in MCAL

Bruce(Shanghai) Liu

Part Number: AM2634

Hi team,

I found an unreasonable place in mcal fls module. In the Fls_Erase(),it is considered to do sector level erase, but it will call Fls_NorErase() which do block erase actually.

I try to do a test, the result is the same with what I described above.

I think we need do 2 separate functions for block and sector erase to avoid confusion.

Hi bruce,

Can you please update the offset from which you're trying to erase please? And also what's the length that got erased?

Thanks

Hi Kowshik,

In terms of parameter, offset=000U and length=64U, which I want to erase 4Kb(a sector), but it erase 64Kb(a block) actually.

BR,

Bruce Liu

Hi bruce,

As discussed, are you seeing normal behaviour when you updated the NOR_BLOCK_ERASE command with the sector erase command?

Thanks

Hi Kowshik,

Yes. It works after updating.

Hi Bruce,

I have raised a internal JIRA as an improvement to fix this [SITARA_MCU_MCAL-4440] Fls Erase function always performs a BLOCK erase - Texas Instruments JIRA

Thanks, I'll be moving this ticket to closure.
