A bit off-topic, but there is an open-source alternative to SAM-BA for the Macintosh called "bossa" (https://ports.macports.org/port/bossa/). I think it can be used to flash the HP-15C CE with the lastest firmware just as one would do with SAM-BA. I could use a Windows computer to update my HP-15C, but this (the computer) is gone now so I will use bossa on the Macintosh for the next one.

This is a good find, but I think it would need the patches from this PR request: https://github.com/shumatech/BOSSA/pull/143

Specifically, the CPU in the HP 15C CE per Wikipedia is an Atmel ATSAM4LC2CA. Its CPUID appears to be 0xAB0A07E0 which the PR adds support for (0xAB0A07E0 & 0x7fffffe0 = 0x2b0a07e0):

Code:


    case 0x2b0a07e0:
        _family = FAMILY_SAM4L;
        flashPtr = new CalwFlash(_samba, "ATSAM4Lx2", 0x0, 256, 512, 1, 16, 0x20001000, 0x20008000, 0x400a0000);
        break;

If anyone manages to patch and build, please report on the result of the flashing.
