i.MX RT 1502 QSPIFLASH Boot

The default PIN MUX :

GPIO-SD-B1-06 -----> L3  ------> FLEXSPI-QSPI-SS0
GPIO-SD-B1-07 -----> L4  ------> FLEXSPI-QSPI-CLK

GPIO-SD-B1-08 -----> P3  ------> FLEXSPI-QSPI-DATA0

GPIO-SD-B1-09 -----> N4  ------> FLEXSPI-QSPI-DATA1

GPIO-SD-B1-10 -----> P4  ------> FLEXSPI-QSPI-DATA2

GPIO-SD-B1-11 -----> P5  ------> FLEXSPI-QSPI-DATA3

 

When I design the board,I change the PIN MUX  :

GPIO-AD-B1-15 -----> J14  ------> FLEXSPI-QSPI-SS0
GPIO-AD-B1-14 -----> G12 ------> FLEXSPI-QSPI-CLK

GPIO-AD-B1-13 -----> H11  ------> FLEXSPI-QSPI-DATA0

GPIO-AD-B1-12 -----> H12  ------> FLEXSPI-QSPI-DATA1

GPIO-AD-B1-11 -----> J13   ------> FLEXSPI-QSPI-DATA2

GPIO-AD-B1-10 -----> L13  ------> FLEXSPI-QSPI-DATA3

 

Now,i can not boot from the new PIN MUX QSPIFLASH,even can not connect to the flash.

Does someone know that how can i download my hex to the flash now?

Thanks!

 

I change the BOOTCFG[2:0] from 000b to 111b,but it can not boot from the secondary pinmux.

 

It dosen't work。Is this a BUG ? if not ,how can i configure the boot_cfg?

Need help,Please.

Thanks.
