RT1051 and QSPI

Hello everybody,

I am currently working on a custom board with RT1051 and a QSPI flash memory - same type than EVKB, just smaller.

We can read and write the board via SWD/JLink, but we are unable to start the board from QSPI despite the fact that we burned the correct fuse (just BT_FUSE_SEL, because the other default values are OK) and that we have BOOT_SEL pins both to GND.

I was unable to understand the problem so far. Hopefully, someone can share his/her experience in order to help me understand what is wrong.
