I tried installing the hardware-only FX chip, but both the Mod chip and the Flash chip were not found when I ran the activator. I have tried resoldering the VCC and GND ports (as instructed in the troubleshooting guide), to no avail.
A few things to note:
- My Arduboy is quite old (it is actually a blue one from 2016) and, unlike new ones, has some rubber pads around the screw sockets in the lower left and upper right. The SDA and SCL connections, as a result, were quite difficult to solder in, but it appears that they look okay. This might still be an issue.
- I ordered a second standard Arduboy (since it was on sale) and another FX chip which just arrived today, and I was able to install it and get the FX loader to fully function, showing that my soldering technique should have worked when I installed the chip in the original Arduboy.
Let me know if a picture or the diagnostic info would be helpful in troubleshooting this issue.
Thanks,
Jackson
