I've not downloaded the new bit files yet. But it needs the 7i90 reset to an epp interface I'd assume in order for mesaflash to be able to reprogram the card, correct? That imply's a complete mechanical disassembly because the 7i90 is at the bottom of a stack of cards, and will need connected to a machine with a parport. With the pi turned upside down, which allows an spi cable only about an inch long. And I am not using any smart serial stuff, my 7i90's gpio's are all directly connected to the hardware. So is it even recommended that I reflash the 7i90 in my lathes application? IOW, if the fixed driver (because apt has updated it,) is used with the unfixed firmware, is there a detectable effect/problem? Because the teardown to do that reflash is a cast iron pita, I'd be time and effort ahead to order another 7i90HD, program it, and just swap it out, I might be able to do that in one long day. Maybe 2, depending on how many times Dee interrupts me as she's home now, but still hopping 4" at a time on her good leg and a walker just to get to the potty chair. So I'm chief cook and bottle washer in addition to potty chair dumper/cleaner. :) What is needed for this, is a mesaflash for spi. Is that even possible to do, Peter?
