Trace code location:

nt dfu_flash_write(uint32_t addr, uint8_t *data, int size)

{

int8_t flash_type = dfu_get_flash_type(addr);

int ret;

uint32_t wr_size;



if (flash_type == DFU_FLASH_TYPE_NOR)

{

    wr_size = rt_flash_write(addr, data, size);

    LOG_D("wr_size:%d!!!!",wr_size);

}

A blocking phenomenon occurs here, causing errors in the subsequent upgrade process.

May I ask, how to optimize and handle this phenomenon?

What software version is being used?

sdk 2.4

sf32lb52-lchspi-ulp: ptab.json modified according to above

I see that in your ptab.json, you changed the max_size of DFU_DOWNLOAD_REGION from 0x120000 to 0x320000， and the end address becomes 0xBA0000**，** if your FS_REGION area is not changed accordingly, it will overwrite the 2MB space from 0x9A0000~0xBA0000 in that area, causing the Flash write problem you mentioned.

Try reverting the download area to its original state, or moving FS_REGION and KVDB together later, or shrinking FS, to see if it solves the problem.
