The boards currently ships with the Android Boot Loader, but replacing this with abl2esp allows writing a EFI System Parition and OS partitions to all of LUN0, and a more UEFI boot experience. A prebuilt version of abl2esp is provided at [1], as abl2esp-v6.elf. With a (very) recent version of QDL, a flash programmer from a Tachyon software release, and a full distro image, this can be achieved with: qdl prog_firehose_ddr.elf write abl_a abl2esp-v6.elf write abl_b abl2esp-v6.elf write 0 image.raw The following firmware files are currently used, on top of what's in linux-firmware already: qcom/qcm6490/particle/tachyon/a660_zap.mbn qcom/qcm6490/particle/tachyon/adsp.mbn qcom/qcm6490/particle/tachyon/cdsp.mbn qcom/qcm6490/particle/tachyon/ipa_fws.mbn qcom/qcm6490/particle/tachyon/modem.mbn In addition to bug fixes that has landed in v6.17-rc this depends on [2], which is available in linux-next.
