Joggler won't Flash

[julzgeraghty]

I noticed on one of Roobarbs! pages on Birdslikewires that the Openpeak image turns off the ability to boot straight from the stick so I went back to an old version of the O2 os. I can now boot off a USB stick and have the Joggler running Roobarbs! Squeezeplayer off a stick. It still won't boot from internal memory though. Any more suggestions?

Are you stating that you can only boot off a memory stick and if you pull the memory stick then you cannot boot into the original Joggler O2 OS?

Your EFI boot flash might be trashed and its an easy fix. Personally I would just take the EFI boot flash out of the working Joggler and test your internal memory. Really if you are careful it takes 10 minutes to test it. If it works then purchase another chip.

From that eBay job lot, I had a Joggler that would appear to flash, but never boot beyond the O2 logo without a USB stick. EFI re-write cured that one. Pete's suggestion to temporarily swap the EFI chip is a good one. Touch a radiator to ground yourself beforehand.

Where my 1GB eMMC had died, I had very obvious errors with both Roobarb's and openpeak's flash tools.

Relating to the 1Gb eMMC you can check it if you can boot into linux. First boot up with a linux stick on the good Joggler and copy out each of the three partitions or the entire disk to a 2nd USB stick. Then go to the non booting flash Joggler, boot into Linux and first do a check on each of the three partitions. If you want then delete all three partitions, write one partition and check it, then delete and write the three partitions back from the backup you did before. If the check disk though doesn't work with the first time you check then your eMMC Gb flash memory is trashed and nothing will fix that other than soldering a new one on the motherboard. But you can continue to boot from the USB stick or just write the Seabios coreboot bios to the EFI flash and boot internally from a USB stick or the PATA port.
