- Thu Sep 08, 2016 3:24 pm #54701 Hi everyone!
I've a custom OTA update code which successfully downloads firmware over mqtt and writes to flash.
However, on calling to system_upgrade_reboot() at last, it either hangs or does not switch to the correct image (user1/user2) even though it attempt to do that at the end of system_upgrade_reboot() call.
I use latest 'esp-open-sdk' with nonos-sdk_v1.5.4, and ESP-12E (NodeMCU) with 32Mbit(1024KB+1024KB) flash map.
Here is what I see on the serial monitor:

1. on user2 as currently active

2. after firmware download and written to the flash, then trying to reboot:

It showing garbage on the serial monitor (I use 74880 as baud rate) - is this due to wdt reset or something else?

Sequence of action on the code is as follows:

system_upgrade_userbin_check()
<calculate address to write new firmware i.e. 0x101000 or 0x01000>
system_upgrade_init();
system_upgrade_flag_set(UPGRADE_FLAG_START);
<write image here using spi_flash_erase_sector() & spi_flash_write() - 4bytes aligned>
<if success call system_upgrade_flag_set(UPGRADE_FLAG_FINISH)>
and call system_upgrade_reboot()


Any help on figuring out the cause would be really appreciated!

Thanks in advance

- Wed Mar 01, 2017 10:18 pm #63214 I'm having the same problem with a 1Mb ESP-07 (viewtopic.php?f=159&t=13973) and the exact same code works on an older 512kb ESP-07.

Did you figure out what's wrong ?
