Yes I do. They are straight from the LPC2292 code, so once they were considered OK. I checked out the the write{s,l,b} functions in asm/io.h, but although they look similar, for some reason they simply don't work. Given the similarities between the write{s,l,b} and the PUT* functions, what is the problem with those? Furthermore, the ARM architecture doesn't use any kind of special instructions for accessing registers, everything is memory mapped.
please use readx/writex
Thanks for the pointer, I'll look into those.
I can't find these functions/macros, but I think you mean the write{b,s,l} macros. As I already indicated in a previous e-mail, they do not work in my code. If I replace, e.g. the PUT32 with writel than the code doesn't run. I will look into that problem after I've finished another project at work.
Kind regards,
