So _that_'s what that bit was all about! Thanks for the pointer. That might well work. But the bit -G turns on also turns _on_ some tests, and modifies others; I don't know whether it would get upset at the Pi Pico's quasi-filesystem. I #if 0ed the 0x55 0xaa test and it then mounted - but crashed the kernel upon trying to unmount after the device reset (which involved disappearing from USB). I may investigate more someday, but probably not soon, since, as I think I said upthread, I've found a more effective workaround (ignore the filesystem entirely). /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mo...@rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
