It took half an hour to complete a pass where no chip was found. The chip is a MX25L4005APC-12G. There was a few "strange" messages, don't know if they are related. The messages are: "Not unmapping zero size at 0xffffffffffffffff" and: """ Probing for ST M25P40-old, 512 kB: sb600_spi_send_command, cmd=9f, writecnt=0, readcnt=3 Writing: SB600 FIFO pointer is 0, wanted 0 Executing: SB600: execute_command timeout! sb600_spi_send_command, cmd=90, writecnt=3, readcnt=2 Writing: [00][00][00] SB600 FIFO pointer corruption!
