DEFlashPartition issue

JinhuaiChen — Fri, 07 Jun 2024 07:52:34 GMT

Hi all

I've executed the function

FLASH_DRV_DEFlashPartition(&gstFlashSSDCfg, 0x02u, 0x08u, 0x0u, false, true)

but now，I want to modify my configuration to 32K eeprom,32k data flash in my product(#S32K144) without erase by J-Link.

It seems that it can be modified by factory mode, who can give me more information or demo project

Hi @JinhuaiChen

It is not possible to update the partition without erase. The only option is to remove current partition by Erase All Blocks Unsecure command or by Erase All Blocks command (in this case, you need to update Flash configuration field appropriately by yourself). And then you can run the partition command again.
