Reboot occurred in system_upgrade_start() for FOTA

2015-07-22T20:24:13+08:00

Hi,

I am using system_upgrade_start() functions for FOTA (Firmware upgrade over-the-air) using the binary files on my own OTA server.

Initially the upgrade process was successful, but it began to fail (reset occurred) to have repeated several times.

Code:


 ets Jan  8 2013,rst cause:4, boot mode:(3,0)

wdt reset
load 0x40100000, len 1396, room 16 
tail 4
chksum 0x89
load 0x3ffe8000, len 776, room 4 
tail 4
chksum 0xe8
load 0x3ffe8308, len 540, room 4 
tail 8
chksum 0xc0
csum 0xc0

2nd boot version : 1.4(b1)
  SPI Speed      : 26.7MHz
  SPI Mode       : QIO
  SPI Flash Size & Map: 16Mbit(512KB+512KB)
jump to run user2 @ 81000

I use SDK 1.2.0.
The size of the binary file for upgrade is 306272 Bytes.

Please confirm it.
