[Avila] Always checksum error after flashing new redboot image

[Tim Harvey]

Jose,

I've noticed a few issues with the new bootloader that you should watch out for:
  - after updating the eeprom the bootloader does not 're-read' the
values so you have to power-cycle the board for the new settings to
take (can't just use the redboot 'reset' command) - this may be your
issue

  - if the bootloader does not detect new eeprom config it prompts you for settings but the 'boot_script_data' var (the boot script) gets taken as input to the prompts (not your issue - just an annoyance - simply break out of the prompts and run 'econfig' again)
  - the new flash timings are a bit too strict.  I've seen issues with GW2347's not booting about 20% of the time with the flash timings in the new bootloader (not your issue as your clearly booting)

Subject: [Avila] Always checksum error after flashing new redboot image

Hi,

After flashing a new redboot (2.04) to a GW-2348-4 board, when booting, 
the redboot always prompts a message about error in eeprom checksum, 
with the execution of econfig tool in order to write the adequate values 
into the eeprom (GPIO0/5-14 and model). However, writing new values does 
not solve the problem, because the same error message appears always. 
Also, when executing Linux image, the message “EEPROM checksum error, 
loading Default values” appears.
The same redboot image has been flashed to another 2 identical boards 
without errors and the eeprom tool seems to work properly since memory 
can be read and written from the redboot console.
In addition, flashing the old version from redboot (2.02) works fine and 
images from Linux and rootfs are executed and loaded successfully.
Any suggestions in what can cause the problem?

Regards,

José Luis
