I brought #chubby75 I/O mod PCBs to #37c3
If you want to turn your #Colorlight75 into a general purpose #FPGA platform, drop me a DM.

(edit: spelling)
Recently I've been working on bringing #apolloFPGA to the #rp2040. The USB stack, UART and JTAG scan already work, but I encountered a problem when trying the blinky example.
I really would like to integrate this with my #chubby75 project - chubby hat.

Yesterday I managed to program a Colorlight 5A-75B v7.0 with OpenOCD and a Blue Pill running versaloon.

I just had a successful run with versaloon. I simply checked out v1.0 of the repository and flashed it to a blue pill board. After checking that the device get recognized by my computer with dmesg and lsusb, I connected the JTAG signals and 5V power. I tested the setup with the pin-scan example. Since I had a different version of the board than the author did, I hat to make some changes to the code. <details><summary>git diff</summary>diff --git a/5a-75b/pin-scan/Makefile b/5a-75b/pin-scan/Makefile index 2a870ce..a897...</details>
