Ive been slowly working on an Seq v4+ for the last few weeks, following along hawkeye’s videos and it been going well so far. All the testing along the way has worked ( after a little reflowing here and there on the UI boards).
Today i have been assembling the case. At the stage where it is time to upload the firmware, i am getting no midi ports found in mios studio. I figure no problem, I’ve probably pulled an IDC cable loose along way. Backtrack disassbling and try again without the UI boards in the case and double checking to push in all idc cables. Now I see midi ports again.
For sone reason i thought “lets try installing the seq v4+ firmware now and then build up the case again testing along the way”.
So i follow those instructions, putting the RH harware config in the root (using MIOS studio) and upload the firmware. Upload says successful but nothing happening on the displays. Tried a power cycle, still nothing. Midi ports not showing up. Now i’ve strippped it back to just the Core MCU / PCB and USB PCB , and Res-SD PCB, but still whem connecting the USB to my laptop no midi ports showing up.
The green LED by the SD card lights up and the red power LED on the waveshare.
Im sort of at a loss what to do now- any suggestions?
Feeling somewhat disheartened- I thought I was about to ve finished, but now nothing is working!
