PN7462 booting issue

sanath_rai — Wed, 13 Feb 2019 09:15:34 GMT

Hello ,

I am working on PNEV7462C development board.

I am using MCUXpresso IDE and i have run all the example codes on the board which worked perfectly.

But after i tried to flash the code in to EEPROM using GUI Flash tool and came back to normal debug mode i am unable to run any application it is getting stuck at function phFlashBoot_PreCheck() at line

PH_USER_ASSERT(gpkphCfg_EE_Ctrl_VerInfo->major == PH_FLASHBOOT_SUPPORTED_EEPROM_VERISON_MAJOR);

What might be the issue?

Anything wrong with the FLASH ?

Regards,

Sanath Rai

Hello,

I had used GUI Flash tool to erase and program the Flash.

It may have erased the primary boot loader .Can i flash the boot loader again if yes what is the tool use to do that?
