Extend to support the "kickstart" flow #36

Closed quic-jhugo closed 1 year ago

quic-jhugo commented 1 year ago

QDL implements the sahara protocol which is a core piece of the "kickstart" flow. Kickstart typically doesn't use USB, nor will it use firehose, so the qdl application isn't quite what the kickstart flow needs. Qualcomm Cloud AI 100 is one such device that uses the kickstart flow and would benefit from this support.

this PR breaks old way of using QDL

qdl prod_firehose_ddr.elf ... Can not open (null) ...

quic-jhugo commented 1 year ago

I don't see how, but clearly you are having an issue. Can you provide any additional information? What hardware are you using? Where is firehose coming from? Have you done any debugging?

bmx666 commented 1 year ago

Hi @quic-jhugo

I'm using QDL, QFIL and QPST to flash QCS605, SA8165P and SA8195P Qualcomm boards. All used images like prod_firehose_lite.elf and prod_firehose_ddr.elf are building from QCOM sources.

You mention about "no USB" and usage of socket /dev/mhi0_QAIC_SAHARA, but that is too specific for Qualcomm Cloud AI 100 only. In my case I have no any sockets like /dev/mhi0_QAIC_SAHARA

quic-jhugo commented 1 year ago

@bmx666 Can you post the exact qdl command you are using? Is the only output you get "Can not open (null) "? I'm unable to replicate any kind of issue with the qdl binary. The comments on no usb and /dev/sahara only apply to kickstart, which is not applicable to you as I understand it.

bmx666 commented 1 year ago

@quic-jhugo

nothing special in QDL commands

qdl --debug --storage ufs \
    --include /path/to/images/ \
    /path/to/images/prog_firehose_ddr.mbn \
    /path/to/images/rawprogram_unsparse0.xml \
    /path/to/images/patch0.xml \
    /path/to/images/rawprogram1.xml \
    /path/to/images/patch1.xml \
    ...

qdl --debug --storage emmc \
    --include /path/to/images/ \
    /path/to/images/prog_firehose_ddr.mbn \
    /path/to/images/rawprogram0.xml \
    /path/to/images/patch0.xml

I will add output with PR and without PR tomorrow

Oh, so it is sahara.c which can't open the file. That makes sense, at least from the standpoint that I touched that code. Will have a closer look.

bmx666 commented 1 year ago

Hi @andersson, I'm not sure, but this PR should be reverted until a working solution is implemented. Because many people who use QDL don't know anything about kickstart and most phones support the prog_firehose.elf bootloader. Most of them won't investigate why QDL doesn't work properly and even for me it was surprise because I spent 3 days to figure out why it wasn't working. Sorry, but I also don't get it why this PR was merged so quick without any verification and discussion? Your repo contains a lot of PR which is really useful, but they still in progress since 2022.

andersson commented 1 year ago

Sorry about that @bmx666, and thanks for the log. I've pushed a fix, after testing on a few different boards.
