I'm trying to get the Basic_rBoot_Sample (from Sming 2.1.1) working on a 1MB esp.

I was able to run the first ROM, but as soon as I try an OTA my esp reset:

Code: Select allHello !!
trying to mount spiffs at 40242000, length 65536
fs.start: size:64 Kb, offset:0x42000

wdt reset


My guess is that it is writting at the wrong offset. But I don't really know what I'm doing with these memory numbers

Code: Select allRBOOT_ENABLED = 1
RBOOT_BIG_FLASH = 0
RBOOT_TWO_ROMS = 1
SPI_SIZE        = 1M
SPIFF_SIZE      = 65536
RBOOT_SPIFFS_0  = 0x042000


And my rom1.ld I changed

Code: Select all  irom0_0_seg :                         org = 0x40282010, len = 0x42000


What I'm trying to do is two ROMs, one shared SPIFFS. something like 300k + 300k + 200k if that's possible on 1MB flash.
Does anyone have a working setting ?

- Mon Jan 25, 2016 4:05 pm #39683 OK, my fault. I changed my power supply and that was the cause of the unexpected reset.
Back to normal operation... I will post if I have any progress.
