The first USB drive I used definitely was FAT32 formatted (as it had been FAT formatted initially and I reformatted it). But... it isn't like flaky old USB drives handed out at trade shows not always working as hoped is a new thing
@blogic I look forward to hearing more about the SPI NOR locking mechanism, as I feel that lies at the heart of how I messed up in the first place. It would be good to have clarity of what the jumper does, and how that relates to the Unlock NOR and Lock NOR boot menu items?
I wonder how much it would cost to put the flash memory in a carrier (so a bad flash could just be popped out and replaced if bricked) or a known good dual-partition like Netgear is known for?
Before I knew about UART recovery I'd planned on using JTAG, and ordered a programmer - specifically a Raspberry Pi Debug Probe. I'd decided on that after reading that Serial Wire Debug (SWD) was the standard for programming Arm devices like the SoC in the One. But, it wasn't enough. The OpenOCD scripts I was planning to use expect a JTAG interface, and not (just) SWD.
