Some customers with existing NET+OS firmware are having issues (not booting) when running their firmware (image.bin or rom.bin or both) on new modules delivered after May 2022. Specifically NOK with PN:(1P)50001528-36, where old working SKU hat PN:(1P)50001528-06 was OK (both Digi Connect ME 9210 -C for NET+OS 4MB flash 8MB RAM).
Root cause in most of this cases is that customer did not (correctly) apply the flash patch for Macronix MX29LV32E which was announced back in PCN#180601 June 1st year 2018. Or their firmware build is still based on older sources, even if they patched the NET+OS ESP but not their project.
While the PCN announced new flash chip back in 2018, Digi did not deliver any modules with the new flash chip since that time, because we still had stock of the old flash chips. This means no customer ever had verified with hardware having the new flash chip, that they correctly applied the patch and they evaluate now in 2022/2023 when Digi is finally delivering some modules with this flash part.
Symptom might be that after programming old custom firmware, the firmware does not boot anymore or is throwing an Exception similar to (see serial output after firmware update):
NET+OS Version 7.5.2.2

If you don't have this in your source code, you don't have the latest NET+OS 7.5.2.2 with all PackageManager (PKM) patches applied. You should run the PKM, install all latest patches (specifically Patch version: Flash 1.04 ESP_Plugins 1.02 ) and create a new project and merge your changes from the old into the new project.
During project creation some of the installed source code and libraries are copied into the new project. So updating the ESP with PKM will only update sources and libs for new projects. Existing projects might still use their old sources + libraries.
