Change log as follows:

This is urgent to prevent unit from failing to boot after battery shutdown signal was sent therefore getting in brick state. Instructions will be listed after change log.

2. Improve external battery over discharge protection.

3. Add ability to work on external battery only if a problem is detected in internal battery.

4. Force internal battery charger button in power tab toggles between batteries depending 

    charge levels.

5. Battery monitor logs powermeters, online time, and output status.

 

 

U-boot update instructions:

If your unit is operating normally, please skip step 0.

 

Step 0. On units with unreachable UI, i.e. ping is not working, bricked:

Open the unit and unplug the two sets of cables coming from the internal battery for about 10 secs.

Then replug. After this the unit should be able to boot normally and get ping. 

Don't close the unit yet.

 

II. On units working normally

 

Step 1. Perform the solarbeam fw update using the binary SB.v1.2-beta4.3bb284.171208.0555.bin

Step 2. Remove all loads and other networking devices attached to the unit.

Step 3. Once this fw is updated, please make sure your internal battery has more than 10% of charge before proceeding with u-boot update. Remove all loads and other networking devices attached to the unit.

 

Step 4. Log in through ssh

/sbin/ubupdate -m

 

Step 6. Follow the instructions, answer the 4 questions with: yes 

Step 7. In the last step you will see this message:

[  OK  ] New U-Boot image succesfully written into FLASH
[ Info ] Done! You can now reboot your device!

Step 8. Then run the command:

reboot

 

Step 9. After reboot if you need to extra check you are using the new u-boot, please run

md5sum /dev/mtd0

and the output should be:

a8d19a57420388fb9636cba5bd801108  /dev/mtd0

 

Step 10. Check everything is ok in UI.
