Hi,

I am using STM32f722RE based custom board, while performing the flash erase, getting the following error log in J-Flash V7.52b (*i have also tried latest version of J-Flash but saw same error log).

Erasing chip ...

Flashing bin and hex file is also not working.

i have also verify that is there something wrong with a chip using ST-LINK/V2 and STM32CubeProgrammer, erase and programming the .bin file is working with same chip.

Anyone has idea why it is not working with Segger J-Link Pro.

I have attached the j-Flash project file.
