Hello,
We have a custom board with RT1176 MCU. Our Boot CFG pins are all set to low, when our board is at b10 for the boot mode, which is serial download mode, we can do the following things from the MCUXpresso Secure Provisioning Tool:
When we set the board boot mode to b00 which is boot from fuses, it does not continue from serial download mode since there is no bootable image on the board, as default it should redirect to serial download mode but it won't.
When we try to connect via MCU-link with b01 internal boot mode we get the following result from MCUXpresso:
After this when we set it back to serial download mode b10 again we can connect via MCU-Link from MCUXpresso but when we try to debug it won't even start the program and throws a fault as below:
- What could be our problem here? What are we missing?
- Is there an example that you can suggest that we can directly run the code from internal RAM without using any flash to see any kind of result?
We don't use the same QSPI flash but we configured the custom_flexspi_nor_boot.c for our flash which is AT25SF321B.
Hello Pavel,
Thank you for your answer.
We've tried the project you've suggested but again the same thing happened. We've tried the project at serial download mode if that is relevant. We get the below results. Also flash at the schematic that you've provided is not the same with ours. We have AT25SF321B.
Hello, my name is Pavel, and I will be supporting your case, I reviewed your information could you try to test the example blinky led but for the EVKB RT1176? please, has the same memory that you have.
Best regards,
Pavel
Also, for our Flash AT25SF321B, does default flash driver acceptable?
Also here are the defines for our example project with custom_flexspi_nor_boot.c for our flash. Are these acceptable?
