Updating Firmware - impossible

[kiralikbeyin]

There is no way to update with OTA.

I tried esphttpd example to upload a bin file but it is only for esp32..

There is no solution for firmware update but only HomeACcessoryKid lib worked with under 560k file size..

https://github.com/HomeACcessoryKid/life-cycle-manager/issues/11 My firmware size is 666k

Any idea?

At now OTA cannot work with binary major then half of flash size.

Infact bootloader let startup fist or second partition. If your binary is more then a partition you cannot use OTA functionality.

Ideas Try reduce size You can try compile binary optimized for size the could improve your flash footprint and reduce of some byte. Is possible that optimization reduce size of 3,5% not more. Let try this way and report how many byte you save.

If this is not enough try with readelf and debug elf and a combo of options to dump simbols list and relative size order by biggest. Is. Biggest simbols all required or some simbols are unknown. Try to optimize where is possible.

Last ideas, very complicated. Create a separated binary is a second flash areas. This on lunch reset ram load bss and data section and startup. This separated binary perform OTA update. Is only a Idea.

@AndreaGreco Thanks for reply.

I was using 2 step update with arduino. https://github.com/xoseperez/espurna/wiki/TwoStepUpdates

1-Trigger update with normal 666k firmware. 2-Get an 250k updater firmware. 3-250k updater will get 666k firmware Does it work?

note that i am using https://github.com/SuperHouse/esp-open-rtos/issues/668 https://github.com/apiel/aboot firmware because only this robot.bin works with this lib..

I am on step 3 but it throws

[AndreaGreco]

Try with same firmware flash blink.bin I inside of your firmware. This confirm you that your code works. Obviously after you need reflash with esp tools your firmware.

Let me know

[kiralikbeyin]

@AndreaGreco I already flashed blink.bin it works.

http_client_ota.c firmware is 265k

Not i am trying to find a way to put 666k ... @apiel

aboot.h

//#define ROM_SIZE 0x55000 // 348160 bytes ABOOT ORGINAL
//#define ROM_SIZE 0x42000 // 270336 bytes
//#define ROM_SIZE 0x50000 // 327680 bytes
#define ROM_SIZE 0xAF000 // 716800 bytes

#define ROM_ADDR_1 0x2000
//#define ROM_ADDR_2 ROM_SIZE + ROM_ADDR_1 //ABOOT ORGINAL
//#define ROM_ADDR_2 0x42000
#define ROM_ADDR_2 0x51000

I got "Dowloaded image binary checsum is fallied " error so i changed Rboot_verified to 1 ...

esp-open-rtos/extras/http_client_ota/http_client_ota.c

    Rboot_verified = rboot_verify_image(rboot_config.roms[slot], &boot_dimension, (const char **) &error_message);
    Rboot_verified = 1;

[AndreaGreco]

You must store all code that is execute OTA process All bootloader function all OTA code... In a fixed sector that is not erased during flashing operation.

But, http_ota_client is not written with this purpose.

At now I'm over the beach. Maybe when I back can checkout your source code if possible and try to understand exactly what are you doing. Maybe together can found a solution.

But form here I cannot help you more.

I will back at 26/08

[kiralikbeyin]

ok @AndreaGreco thanks maybe someone reads these before you come back.

I only changed

define ROM_SIZE 0x55000 // 348160 bytes

to

define ROM_SIZE 0x78000 // 491520 bytes

https://github.com/apiel/aboot/blob/master/aboot/aboot.h

453k firmware uploaded (not blink.bin)

but when i try

define ROM_SIZE 0xAF000 // 716800 bytes

Can you give more details about the hardware you try to flash? Cause there is many kind of esp8266 and there is as well different options to flash your hardware depending of the size of his characteristic... For example I had lot issue for getting OTA to work on some sonoff devices and this was the reason why I was writing aboot (heavily inspired by rboot). But eventhough, I never really managed to get stable results, it was somehow working but not all the time. From what I remember, the only way to make OTA working properly was to use an arduino firmware instead of esp-open-rtos. Also using the arduino SDK will make your life much easier since there is much bigger community. Esp-open-rtos is not that's trivial and you might encounter multiple issue that are often difficult to solve. In another way, you will learn a lot as well ;-)

@apiel thanks for reply.

I always use nodemcu v3 (lolin) if code works i try with sonoff or other things. (qio mode works but i will try with dio also for nodemcu)

Your aboot lib works up to 450k firmware.

1-Which seems easy but dont know how to make because arduino use eboot. I am using 666k esp-open-rtos firmware. I can use arduino OTA if i can switch back to esp-open-rtos : 666k esp-open-rtos -> 265k arduino update -> new 667k esp-open-rtos

Two steps update : 1-Trigger update with normal 666k firmware. 2-Get an 265k updater firmware. 3-265k updater will get new 667k firmware

2-aboot modification and https://github.com/SuperHouse/esp-open-rtos/blob/master/examples/http_client_ota/http_get.c

This code works with http_get.c example. blink and a 450k firmware is ok..

• i dont want to learn more ota shit :) 10 days enough

10 days is nothing... OTA and bootloader are not that simple.

If your code is working on nodemcu, it will not necessarily work on sonoff. Some of the sonoff have very small memory size. Also some version are using 8266, some 8285... The basic sonoff, with 1 relay has different versions, with different type of memory. If I remember correctly, you have to flash them in dout.

You seem to have a problem of memory size, if I remember correctly rboot split the memory in 2 equivalent size space so this might not fit for you. But nothing stop you to customize rboot to use fix sizes. After you could try to have small ota firmware on one first boot position and then the big firmware on the second position, and keep it fix. So when you run your ota update it would always go on the second boot position. Even if theoretically this could work, it might still be buggy, because of erasing and writing issue that sometimes randomly happen. I think I was able to get some better result by erasing memory when firmware start before anything else. If you manage to get all that stuff working well would be great that you write an article and share it with us ;-)

Last thing, you should seriously think about to reduce the size of your big firmware. Be careful with this microcontroller, even if it's super powerful don't try to do to much, try to keep simple. Especially try to avoid speudo multitasking that's come with rtos, because it's not the purpose of this microcontroller.
