Currently, IronOS increases the tip resistance by 0.5 ohms for the purposes of USB-PD negotiation. On the Pinecil V2, this can cause issues with power supplies that only supply 60W, such as the Framework 60W supply. At 6.2 ohms, 20V will produce 3.2A, but at 6.7 ohms it will produce 2.985 ohms. This 0.5 ohms increase will cause the V2 to negotiate 20V, draw more than 3A, and trip the overcurrent protection, causing it to reboot. Removing this increase will therefore cause it to fall back to the next highest voltage it can achieve.
