flashiap MCX A in small blocks

berndgrossmann — Fri, 06 Dec 2024 06:49:52 GMT

I try to run flashiap several times but failed second time.

I need to program some small blocks of flash memory.

Here is the output of the modified demo application and source code.

Hello @berndgrossmann

Please debug step by step to check when it failed? Run to which code? And take a screenshot show the failed information.

The return, fail Code is 0x65 after erase.

Is it possilble zu erase the flash in kFLASH_PropertyPflashPageSize = 0x80 or kFLASH_PropertyPflashSectorSize = 8192?

Hello @berndgrossmann

The minimum erase size is one sector, which is 8 KB. You can also read the sector size using the following function:

FLASH_API->flash_get_property(&s_flashDriver, kFLASH_PropertyPflashSectorSize, &pflashSectorSize);

Ensure that the erase size is aligned to the sector size. Based on the returned error code 0x65, it appears that the issue is due to the flash erase size not being aligned.
