[BUG] FLSUN HISPEED Stuck in boot loop with SD inserted #21524

Closed Savage79 closed 1 year ago

Savage79 commented 3 years ago

Did you test the latest bugfix-2.0.x code?

Yes, and the problem still exists.

Bug Description

Newest Marlin Bugfix downloaded April 2/2021. Changed Env. to accommodate FLSUN_Hispeed motherboard. Compiles no errors, copied .bin file to SD card, updates firmware, then gets stuck on Marlin boot screen, reboots and repeats.

Bug Timeline

Unknown

Expected behavior

Expected to finish update cycle with SD card inserted.

Actual behavior

Boot loop with SD card left in, NO SD card will boot as required

Steps to Reproduce

  1. compiled firmware as I normally do.
  2. copy Robin_mini.bin to SD card and proceeded to update motherboard
  3. get stuck on Marlin Boot screen, last 10 seconds, reboots and repeats

Version of Marlin Firmware

Marlin Bugfix 2.0.X

Printer model

Flsun QQS Pro

Electronics

Flsun HISPEED V1

Add-ons

TMC2208 in UART

Your Slicer

Prusa Slicer

Host Software

OctoPrint

If SD card is left in the motherboard it will remain in a boot-loop, however when card is removed boots as normal.

I have tracked commit 6e0b79a to be the root cause of this issue. Pulling the latest commit of Bugfix Branch "Bump distribution date (2021-04-03)" (dd76a50) and reverting the commit fixes the issue.

@chrisjenda thanks! I was suspecting of this too. But I didn’t had time to check.

If you don’t mind to test, I can send you a PR.

Probably it’s failing to use 4 bit.

chrisjenda commented 3 years ago

I am 100% free to test anything to get this to work! I'll give that PR a go!

Hello, I also had this problem that I solved by commenting in the line "//#define SDIO_READ_RETRIES 16" of the PINS file. I have not revalidated it since.

petergebruers commented 3 years ago

I can confirm the problem (branch bugfix-2.0.x Commit 0bd113b9) causes a boot loop on my QQ-S Pro if I leave the SD card in the printer. Tried 2 different cards 4GB white label vs Samsung 32 GB.

I solved by commenting in the line "//#define SDIO_READ_RETRIES 16" of the PINS file.

I can confirm that this fixes the boot loop for me as well.

I only started using Marlin a week ago on my first 3d printer, I cannot add much weight to this discussion. I do toy with MCUs and I am wondering why "16" instead of "3" causes is issues, or why it was set to 16 in the first place (I ran git blame, does not give a hint). So consider this to be "a vote up" for that solution from "an informed noob"

I have same problem on BOARD_FLSUN_HISPEED FLSUN HiSpeedV1 STM32F103VET6 with latest bug-fix

//#define SDIO_READ_RETRIES 16 don`t help me without RESET EEPROM, after reset eeprom boot all OK!

tpruvot commented 3 years ago

You can try to reduce the clock here : Marlin/src/pins/stm32f1/pins_FLSUN_HISPEED.h:258: #define SDIO_CLOCK 4500000 // 4.5 MHz

But your case may be due to the quality of your SD card or just to some errors on it, in general a fresh format fixes the problem too...

a common cheap SD card (not latest ones) can run between 18 and 20MHz if properly wired (not on a long flat cable without shielding)
