bootloader issue, isn't it. I don't know exactly what "internal boot mode" means, but assuming the ROM code doesn't make any output to UART1 at least this clock smells like a bootloader problem. If you're conviced this is a chip problem, did you consider to contact FSL about it? Best regards Uwe -- Pengutronix e.K. | Uwe Kleine-König | Industrial Linux Solutions | http://www.pengutronix.de/ |
