RT1062 EVK GPIO function issue.

Hi Sir,

I try to use RT1062 EVK (Rev-A2) to config GPIO_SD_B1_05 and GPIO_SD_B1_03 to GPIO.

But, it will fail on hardfault.

I import the SDK sample code (evkmimxrt1060_iled_blinky), and modify the GPIO setting by GPIO config tool and generate the code.

Note: My FW is boot from SPI-ROM (0x60000000).

Does the GPIO_SD_B1_05 and GPIO_SD_B1_03 set to GPO(Alt5)?

You are using the flash related pins.

To the EVK QSPI, it is not use B port, so GPIO_SD_B1_03 maybe OK.

But, you use the GPIO_SD_B1_05, which is the DQS pin, it will influence the flexSPI communication.

Please check the datasheet:

If you use the DQS pin, configure to the looped back interrnally, and the flexspi clock frequency limit to 60Mhz.

Wish it helps you!

Best Regards,
