Could it be that the Read JEDEC ID command is not executed by the OTP code?
We know that the OTP code will (successfully) read a large chunk of data from the flash.
Perhaps that code is executed and it tries to read the remainder of the data from the flash.
Consider that after a period of inactivity following that first read, all subsequent reads from the flash happen at a much higher clock rate.
Also consider that the USB will enumerate.
Thank you very much kyeongjinjang for your effort.
