Х5 транспорт приложение ошибка 2209

I am facing the same errors, tried with TMC2208 and TMC2209 on SKR1.1
On the Scope i can see data beeing sent to the drivers, but LCD says connection error.

Installed Klipper on the same Board, 2 x TMC2209 + 1X TMC2208 on a single wire working without problems. So it is a bug in Marlin.

afaik SKR Mini baords and btt boards with stm32 mcus need BTT version of TMCStepper.
what exactly it changed I don’t know but I know it works on my SKR Mini e3 DIP when the normal one does not… https://github.com/bigtreetech/TMCStepper/
also to compile with that lib you need to ass -DHAVE_SW_SERIAL to build flags.

Hmmm… I’m having a similar problem on RAMPS/Re-ARM but since this is the first time I’ve used TMC drivers I don’t know if it’s a bug or something I’m doing wrong.
I’m using a single pin for both RX and TX which should work…

My problem seemed to involve using 1-wire. It didn’t work for me at all — I had to use a Y lead and two separate pins on the board for the connection to succeed.

If I replace TMCSteppers with the one from BigTreeTech, I get an error and the build fails:

collect2: error: ld returned 1 exit status
*** [.pio/build/BIGTREE SKR MINI/firmware.elf] Error 1

If I replace TMCSteppers with the one from BigTreeTech, I get an error and the build fails:

did you also add -DHAVE_SW_SERIAL to build flags? this seems to be a must if you have bigtreetechs tmcstepper lib

No with the flag it worked, thank you

The TMCStepper library from BTT implements the software serial library methods. This is required to comunicate with the TMC uart drivers I their boards.
The HAL STM32F1 in Marlin firmware implements dummy methods for this library.

• Using original Marlin firmware without replacing the TMCSTEPPER library will result in connection error due to the dummy software serial methods
• Using BTT TMCStepper library in original Marlin firmware results in build errors due to redefining Software Serial library methods

Adding -DHAVE_SW_SERIAL to build flags as stated earlier in this issue ignores the Dummy software serial library from Marlin so the build works and the TMC Connection error goes away.

Should Marlin implement the real software serial library for STM32F1 ?

PS: my test case is running SKR E3 DIP with tmc2208s

I followed the same steps.
Get the same errors

SKR1.3 + 2209

Same error on SKR 1.3 lcd says tmc connection error
If i do a M122 It reads the 2208 drivers but get X 0x00:00:00:00 Bad response!
Testing X connection… Error: All LOW

only have 1 2208 driver in my test bench

and cant jog my X axis from lcd.

How about SERIAL_PORT 2?

but it moves all the axis and homes fine.

Please try M122, because drivers will work even without uart…

It’ll be later tonight before I can try that.

Yep. My bad… Forgot about jumpers under drivers 🤣 (2209 seems also fine)

@boelle, skr 1.3 + 2209/2208 = all fine

i will assume the issue is not present anymore and close

if issue is still there we can reopen

how is this fixed? I having same problem, All LOW TMC connection error.

Hi, I’ve an SKR MINI v1.1 (not E3) with TMC2209 and I’m looking for more detailed infos. I’ve everything up to date, using standard libs coming with marlin. I’ve tried defining serialtx and rx pin on pins..-.h then connecting jumpers between that pin and the PDN_UART pin on stepper and I was getting TMC CONNECTION ERROR.
Can I use every pin available on the board (obviously not the filtered ones)? Have I to add the -DHAVE_SW_SERIAL flag?

Sorry but I can see no fix.

@RavaszEmber & @Lechuck7, I suggest you use one of the available support forums to seek help solving your problem. You are using a very common hardware combination so it seems most likely this is a configuration problem and not a Marlin issue. Make sure you are using Marlin 2.0.1, then seek help on Facebook, Discord, RepRap, etc.

I wouldn’t expect any action on this closed issue. Even if the result of support attempts is that there is a Marlin bug, I think it should be a new issue rather than attached to the tail of an old closed issue.

Thanks, kinda new to the Marlin github so didn’t know where to look for help.
Found the solution if anyone’s wondering, I was running the board on usb power when it needed the external power supply.

Thanks, kinda new to the Marlin github so didn’t know where to look for help.

The README.md at the root of the Git Repo has links for several support resources. They are also displayed when you try to create a new issue. Glad you figured out the problem. I know I’ve done exactly the same thing.

Hi I have some question about mks_robin_nano board. I have managed to connect and successfully set up four TMC2209 on this board using bigtreetech TMCStepper library and -DHAVE_SW_SERIAL flag. But this library is outdated… I don’t get why SoftwareSerial or similar methods can’t be implemented while it’s working when using a different library with it.

Will this be resolved somehow in the future, so we can use latest TMC library? Or am I missing something and I should use hardware serial on this board?

@pertzmax, I suggest you try using the SoftwareSerialM library, as is done for the STM32F103RC_bigtree environment.

I did not do this for MKS boards because I did not have any of them to test with, and I wasn’t sure if it would work properly. There is a possibility of timer conflicts on boards, and I didn’t know what to select for any MKS boards.

The SoftwareSerialM timer number is defined by adding an -DSS_TIMER=4 item to build flags, as seen in the STM32F103RC_bigtree. If the BTT TMCStepper was working for you than you can probably use the same value (4) as the BTT boards.

If you confirm that SoftwareSerialM works proeprly with your boards, you should open a pull request to add that configuration for your environment, so others can benefit from it.

@sjasonsmith Thank You for tips, I will test Your solution and report soon!

EDIT: That was easy — It worked like a charm! I will share it soon

Best regards from Poland,
Artur Petrzak

can anyone walk a layman through the process of adding this -dss timer=4 line? I am also getting the tmc connection error, and I cannot figure things out

SKR 1.3 should not need that — that setting is specific for STM32 processors and does not apply to the LPC1768 on the SKR 1.3.

Come on to the Marlin Discord and we’ll try to help you get it working.

I have the same error with the integrated drivers 2209 in the SKR mini E3 V1.2 Board. I do not dig into programming, so it is difficult for me to understand when you talk about some libraries, etc. Just tell me what need to write to make it work. If you know.
With the original firmware, the motors worked, moved, but after installing the latest Marlin, this error appeared. So I suspect that the Board is connected correctly. Unfortunately I don’t have the original firmware =((

I fixed it. Most likely, the problem was in the wrong name of the Board(although I’m not sure, I didn’t return it). I wrote the name like this — #define MOTHERBOARD BOARD_BTT_SKR_MINI_E3_V1_2
