Something Interesting…
… again ;) - I’m currently trying to figure our why the interaction with the TSerialChip crashes when talking to a PCMCIA card as opposed to the internal Bluetooth module. Seems that it’s not the actual interaction with the chip (the functions in the TSerialChip16450 class are quite simple), but it’s a general problem with the interrupts they cause. Something that could as well happen with the internal module. Initializing the chip generates interrupts pretty much right away, and the problem is that accessing my interrupt handling code causes a page fault, probably because it hasn’t been loaded yet. An easy way around that would be to force it to load by referring to it explicitly, but that’s not terribly elegant. I think that Paul has hit the same problem in the ATA driver much earlier than I did, so maybe I’ll check if I can use his workarounds as well. One problem might be however that Blunt 2 is not produced using Packer, instead it’s a regular Newton Toolkit project.
