Failing to build Sharp drivers Bookworm Lite 64bit

[dude363635]

It was building but it errored out with somethig about files not existing
Hardware:
Pi Zero 2 W
Clean install of Pi OS Lite 64bit straight from Imager
Running off seperate power supply to ensure no power loss (3A max)

Heres the error from terminal once it started trying to build sharp drivers (ctrl+c ctrl+v)

Issue received. Congratulations on getting your beepy power supply working again! I will test the glowfire build script against the version of Raspberry Pi OS Lite 64-bit, deployed by the current Raspberry Pi Imager 1.8.5.
TODO related to this issue: I am also going to reduce the spi-max-frequency to be within Sharp specifications. The current LCD SPI frequency is faster than spec, causing unneccesary load on the LCD controller, as well as increased RF generation.

ETA for next update is 48 hours (2025-05-18).

[dude363635]

Thankyou! Alright cool, I'm testing it again now anyway just in case. I will report back if the problem stays or the error is different. Thanks for replying so fast!

[dude363635]

Same error occured just now, I watched the whole process to make sure

[hack-shack]

Successfully reproduced issue on test hardware.

TL;DR: Testing fix internally; ETA for resolution (in glowfire) is 2 weeks (2025-06-01). This ETA is mine, and independent of ardangelo's work.

CAUSE:
There are 2 causes of this issue. Function 'drm_fb_xrgb8888_to_gray8' now requires a conversion state to be passed to it as of Linux 6.8, and fbdev_generic has been renamed to fbdev_ttm as of Linux 6.11.

FIX:

• 4 weeks ago, Kiboneu identified the issue and created a fix. It is pull request #15. The pull request has not been merged yet; it introduces the 'drm_format_conv_state' function, and requires testing.
• 2 weeks ago, Ardangelo began testing Kiboneu's fix.
• I examined Kiboneu's fix and will also test it internally. (See 'Immediate Workaround' section below.)

PLAN:

• sharp-drm-driver is GPL-2.0 licensed, and must be fixed within its own codebase (outside glowfire) in order to remain compliant with GPL-2.0.
• My primary plan is to wait for ardangelo to merge the fix. Then I can update the glowfire install script to install the fixed version from their repository. This is clean and future-proof.
• My contingency plan is to fork the sharp-drm-driver, apply the fix there, and have glowfire install it separately. This is not as future-proof, as I consider ardangelo's sharp-drm-driver repository to be the authoritative source for the Sharp Memory LCD Linux driver.

If you need the driver working immediately, follow one of the two workarounds below. Both methods consist of patching the downloaded driver, and reinstalling it from the glowfire install script.

SIMPLER WORKAROUND (CHANGE REPOSITORY URL):
This replaces ardangelo's repository with Kiboneu's repository, containing the fixed version of sharp-drm-driver.

• Edit ~/glowfire/beepy-sdk/build-sdk.py
• Search around line #480 for the URL: https://github.com/ardangelo/sharp-drm-driver
• Replace the URL with: https://github.com/Kiboneu/sharp-drm-driver
• Search around line #482 for the hash "e65472734decd59450e2448d1218c4f69babcea8" corresponding to ardangelo's commit on 2024-04-30. Replace it with Kiboneu's hash from commit made on 2025-04-31: "ea98230f3b1ff9da993c85c8aa958d338bdd1847"
• On the Pi, delete the directory: ~/glowfire/beepy-sdk/src/sharp-drm-driver
• Re-run make-glowfire.py. It will detect the missing sharp-drm-driver and download it from Kiboneu's repository.
  NOTE: This may fail later on, during the configuration stage. But it may be faster than the manual method.

ALTERNATIVE WORKAROUND (MANUALLY PATCH FILE):
This is how one would manually apply Kiboneu's fix. I have not tested it yet.
It assumes the glowfire install script has run, and failed at the point dude363635 described above.
At this point, the driver has been downloaded to the Pi; you will apply the fix to the cached download.

• On the Pi, edit the file ~/glowfire/beepy-sdk/src/sharp-drm-driver/src/drm_iface.c
• Modify it as per the diff in pull request #15.
• After saving this file, re-run make-glowfire.py as per glowfire's README.

It will reinstall the driver, using the patches you have made.
Glowfire builds RP2040 firmware every time. This takes ~20 minutes before it gets to the sharp-drm-driver install. If time is critical, you can skip the 20-minute RP2040 firmware build process by commenting it out:

• On the Pi, edit the file ~/glowfire/beepy-sdk/build-sdk.py
• Around line #961, search for "build_ardangelo_rp2040_firmware" and comment it out with a #.
• After saving this file, re-run make-glowfire.py

Fix ETA: 48 hours (2025-05-19)
I have confirmed that changing the repository URL to Kiboneu's repository fixes the issue. (See "Simpler Workaround," above.) The driver installs, and the Sharp Memory LCD works.
After testing, I will apply this fix to glowfire source code and update this ticket when complete.

[hack-shack]

All internal tests passed. Uploaded fix to official glowfire GitHub repo. Performing final test before closing this ticket.
Thanks for keeping quality high by filing this bug report.

Thanks for the work!

Closing issue. Glowfire now successfully installs Sharp video driver on Debian Bookworm.
