[BUG] Ender 5 Pro does not start with Marlin 2.1.2.4

[mlutescu]

Did you test the latest bugfix-2.1.x code?

Yes, and the problem still exists.

Bug Description

In fact, I could not compile the bugfix-2.1.x branch.

The behaviour is exactly the one described in issue #22898: the printer is looping between the "Ender" screen and the "Marlin" screen iff the SD Card is inserted. If the SD Card is taken out then imediately the loop stops and the device boots correcly. I suspect this might be a regression. The configuration files are copied from config/examples/Creality/Ender-5 Pro/CrealityV422 in the example configurations bundle.

Bug Timeline

in release 2.1.2.4. In release 2.1.2.3 it works correctly.

Expected behavior

I expect the printer to boot with the SD Card inserted.

Actual behavior

I have to take out the SD Card for the printer to boot

Please download bugfix-2.1.x to test with the latest code and let us know if you're still having this issue.

I confirm the bug does NOT reproduce with branch bugfix-2.1.x. In the initial report I mentioned I could not compile the code from branch bugfix-2.1.x but I did not realise I had to copy the config files for this branch too (I errorneosly used the config files from the 2.1.2.4 bundle).

There are several build environments for this controller, which of the following did you use?
STM32F103RE_creality
STM32F103RE_creality_xfer
STM32F103RC_creality
STM32F103RC_creality_xfer
STM32F103RE_creality_maple

Also chip do you have on your controller so we can try and replicate?
STM32F103RET6 or STM32F103RCT6 or one of those GD32 clones.

[mlutescu]

@ellensp STM32F103RE_creality is the environment and I don't know what is the chip of the controller. Is any method to find the chip version without disassembling the printer? (I would rather not do this. As long as the bug does not reproduce on branch bugfix-2.1.x, this is good enough for me)

I just tried 2.1.2.4 on my STM32F103RET6 creality v4.2.2
It booted fine, sdcard is still in the sdcard slot
rebooted without sdcard,
rebooted with scard in slot again, no issues
