[Solved] Cannot boot user2

[clinkme]

I have ESP-01E with 1024 kB flash size. My firmware uses OTA (no upgrade server,
just writing data from web to the right address of flash - 0x1000 for user1 or 0x81000 for user2,
and then call system_upgrade_flag_set(UPGRADE_FLAG_FINISH);).

I get the strange error code when trying to boot from user2.bin when using flash map
8Mbit(512KB+512KB).

Code: Select all

E:M 0


When I revert the boot to user1.bin (erasing 0xFE000 sector), the chip boots OK from user1.bin.
Also, when I use flash map 8Mbit(256KB+256KB), both user1.bin & user2.bin are working OK.

Code: Select all

Solved. There was a problem in makefile (user1 was linked for 1024k flash, but user2 for 512k).

Hi,

Please call "make clean" first to delete the files generated in previous compilation (user1.bin), then compile user2.bin.

Thanks for your interest in ESP8266 !
