BomberHQ Posted December 5, 2020 Share Posted December 5, 2020 Hey folks, Just built my first PIN2DMD using a V4 shield and Nucleo-F439 (for a real pin, Data East, 128x32) and was getting very strange startup issues (see video). The only way I could get it to start was to press the reset button on the Nucleo board (I press it at about 15 seconds). This is my first PIN2DMD, so I thought it must be my soldering, a faulty component or the power supply, but everything checked out. I even re-flashed the ST Link and PIN2DMD firmware with the same result. Finally, I decided to load an earlier version of the ST-Link firmware and it worked. Im now using V2.J35.M26 I cant tell if this affects other configs, but it may help someone! 20201204_223041.mp4 Link to comment Share on other sites More sharing options...
aganyte Posted August 30, 2022 Share Posted August 30, 2022 I'm having the exact same problem more and more often. Currently, I have 3 new nucleos doing the same thing. I have already tried to downgrade the st-link but without success. I tried with firmware 3.5 and 4.0...same problem. An idea ? Link to comment Share on other sites More sharing options...
aganyte Posted August 30, 2022 Share Posted August 30, 2022 Interesting fact, the pin2dmd starts without reset if I plug it on computer USB. Link to comment Share on other sites More sharing options...

aganyte Posted August 30, 2022 Share Posted August 30, 2022 @lucky1 This can help ? https://community.st.com/s/question/0D53W00000kwmMZSAY/nucleo-board-stuck-when-starting-without-usb-connection Link to comment Share on other sites More sharing options...
aganyte Posted August 30, 2022 Share Posted August 30, 2022 I just tried with version 3.2 and got the same problem. Then I tested 2.68 and got a slight improvement. The pin2dmd starts alone but with a display bug, if I reset, the bug goes away. @lucky1 I hope this can help. Link to comment Share on other sites More sharing options...
aganyte Posted August 31, 2022 Share Posted August 31, 2022 Resolved. This thread gave me the solution https://community.st.com/s/question/0D53W00000GXVZMSA5/mco-clock-issue-in-stlink-firmware-v2j37m26 I had tried to downgrade ST-Link but with a not old enough firmware. I found an older ST-link utility on my NAS (V2.J34.M26). Now everything is working fine. Link to comment Share on other sites More sharing options...

I found an older ST-link utility on my NAS (V2.J34.M26). Now everything is working fine. I added the recommended HSE startup timout change to the HAL config. Funny thing is that STM32H7 already is set to 5000 and the old F4 StandardPeripheral Lib had 0x500 set as hex value which is 1280 instead of the 300 in the latest HAL ???!!! As it does not do any harm I set it to 5000 for all CPU types in the bootloader and the pin2dmd firmware for release V4.41 which is now on github.

You need to update/downgrade your ST-LINK firmware as described above and on pin2dmd.com Link to comment Share on other sites More sharing options...

Content Provider lucky1 Posted January 4, 2023 Content Provider Share Posted January 4, 2023 According to the first post, this is the version that should work stsw-link007_stlink_v2.35.26.zip Link to comment Share on other sites More sharing options...
