[BUG] SD Card Not detected on STM32F103VE

[therealalexschwartz]

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

Yes, and the problem still exists.

Bug Description

Hello all,

I have a Longer LK4 with a stock STM32F103VT06 chip. I used the prebuilt Marlin Binary from here but was unable to build from source and make changes after I noticed some bugs.

I'm attempting to port those changes to the 2.1.x version so I am able to run the latest and hopefully contribute back my findings. I have been able to get everything working except the onboard SD Card slot.

The printer fails to detect an SD card and when attached over USB console I see it echo out "No SD Card Detected". I can confirm my SD card works as when I fall back to the pre-compiled version I am able to print from the same SD Card.

I enabled SD Card support in the configurations as well as in the advanced config file specifying onboard. Ive attempted various things found in other issues but with no success. I am unable to find what the original author did to enable SD card support if its a HAL file or a custom pins.h they wrote but so far all my attempts have failed. Hoping maybe someone knows where I should be looking to emulate what they did.

Any and all help would be greatly appreciated as after this point I am hoping the whole printer will be functional.

I am using the maple build, as when I use the non maple build I get a boot loop.

Build Command: platformio run --environment STM32F103VE_longer_maple

Thank you!

Not sure if this info is helpful but here is the terminal output I see when I attach it to octopi

Hey, I have the same problem! But with the new 2.1.2.0 build on a Alfawise U20+. Is there a Bugfix or ideas to solve the Problem?

[Wuerfelix]

I found the problem. The #define ONBOARD_SDIO entry was in src\pins. stm32f1\pins_LONGER3D_LK.hlonger.h missing
