After performing a UDS‑based bootloader flash update using INCA as the host PC, a flash failure occurred on one occasion. The memory range 0x440020‑0x440027 shows '?? '. What are the possible root causes?

Hi @代码织梦师,
I understand that the application is located at 0x440000.
However, where is the bootloader located? Is it in the same flash block?
If so, could you use a different flash block or place the flash driver in SRAM to avoid RWW issues?
At address 0x440020, there is an uncorrectable ECC error. This can occur if the flash sector was not properly erased before programming.
Therefore, please ensure that the sector is erased before programming and that any potential RWW issues are avoided.
Regards,
Daniel
