I have a curious problem:
I'm using a NAND-Flash via FlexSPI in parallel to a NOR-Flash.
It works fine when i
1. download the program via the MCUXpresso IDE GUI Flash Tool (without reset) using the standard NOR-flash driver.
2. then i force a POR via pulling the POR_B pin to ground manually.
If i power cycle the device and then force a POR the NAND-Flash doesn't work anymore.
So i'm wondering what the difference between the 2 versions of reset might be. In both cases i force a POR which should, as i understand it, reset all SoC modules.
One obvious difference is that the NOR-flash driver isn't loaded in case (B). But whatever the driver does, it shouldn't survive the POR.
Maybe someone has an idea, what the problem might be.
