ESP8266 2MB + OTA

[JulienInnovel]

Hello everyone,

I'm using an ESP-WROOM-02 (ESP8266 + 2MB of SPI flash).
I'm trying to do OTA tests with mode 512KB + 512KB, to have 1024KB of user data (I have some data do store into flash and I don't want to erase them with OTA, user data stored at @ 0x100000).

I build my first firmware (V1) with linker script "eagle.app.v6.new.2048.ld", option "16m" (not "16m-c1").
I flash my ESP with ESP FLASH TOOL with this parameters :
SPI speed : 40MHz
SPI mode : QIO
Flash size : 16m
and files :
boot_v1.7.bin @0x00000
user1.bin @0x01000
blank.bin @0x1fb000
esp_init_data_default.bin @0x1fc000
blank.bin @0x1fe000

My ESP start correctly (USART prompt ) :

Now, I want to upgrade my ESP by OTA to firmware version 2 (same as version 1 but only version number has changed) :
It's working perfectly, reboot and prompt this :
ets Jan 8 2013,rst cause:2, boot mode:(3,6)

phy ver: 1134_0, pp ver: 10.2

Now, I want to upgrade to the firmware version 3 (same has others, but only version number changed to 3) :
GET /user1.bin HTTP/1.0

And nothing else.... Reboot it self and only print this :

And my ESP is broken...
I must erase all, and flash it again.

It seems like the firmware 2 is erasing itself or something else..

Any one have any idea ?
Thanks

I just went through some OTA troubleshooting with another member on the forum here. Want to do a skype chat and I can take a look and help you fix it? I have some cycles starting thursday night PST.

If I use the linker for 1MB (512+512), it seems to work !
I have the bootloader for 16Mbit (512 + 512) and I can use OTA to flash firmware and automatically jump to user 1 or user 2, and have a user data flash at the end (from @0x100000 to @0x1FC000).

But, why I must use the 1MB linker ?
The linker for 2MB can't do 512+512 ?

Did you select the 16Mbit on your flash download tool while downing?
And you should note that the system parameter area is always the last 4 or 5 sectors of your flash (16Mbit), you should not save any user data there.

Hi,

Yes, I select the 16Mbit flash when I download the firmware.
My user data selection is from @0x100000 to @0x1FC000 (like defined in the IOT SDK USER MANUAL).
