Hello,
After making the necessary hardware adjustments to use the Octal Flash on the IMXRT1170 EVKB, I started software tests. I made the necessary adjustments with the MCU BootUtility program, uploaded my program code to octal flash and ran it successfully(led blink). Afterwards, I started testing on the MCUXpresso ide. After making the necessary adjustments here (FCB and Flash Driver update), I can successfully load and debug the code on the completely erased (mass-erase) octal flash via the LinkServer debugger. However, when I cut off the power to the EVKB and try to load the code again with the debugger, I get the error "Flash Driver describes no sectors at its base address". But if I do mass erase and try to debug again, I can debug with LinkServer again. Can you help with this? I will insert my nor_flash_config code below.
