I want to enter the Serial Downloader mode and use the NXP Boot Utility through the serial port.

However, the SDP_DISABLE, UART_SDP_DISABLE, and FORCE_INTERNAL_BOOT fuses of my RT1170 are set to 1.

My RT1170 program has a problem and I need to connect the NXP Boot Utility in the Serial Downloader mode to read the FLASH.

How can I enter the Serial Downloader mode when the SDP_DISABLE, UART_SDP_DISABLE, and FORCE_INTERNAL_BOOT fuses are set to 1?

Unfortunately, once the SDP_Disable fuse is blown, it is no longer possible to enter Serial Download mode. I apologize for any inconvenience this may cause.

Best regards,
Omar
