Fails to program large disjoint image? #23

Closed thejpster closed 9 months ago

thejpster commented 1 year ago

I tried to flash https://github.com/Neotron-Compute/Neotron-Pico-BIOS and it failed - I got a hardfault jumping from the BIOS to the OS, indicating the OS was not flashed correctly.

I flashed the same ELF with the official elf2uf2 tool and it worked fine.

I suspect it may be because of the large gap between the end of one part of my binary and the start of the next.

In case it's still relevant, the UF2 bootloader of the pico has a bug which breaks writing of UF2 files with partial sectors (https://datasheets.raspberrypi.com/rp2040/rp2040-datasheet.pdf#errata-e14). You can use #22 which implements filling up partial sectors with zero pages.
