Did you use the Thumb ISA for the ARM ? Same is said to be more compact than ARM32. With a slow memory interface (regarding CPU speed) Thumb might be faster, too. -Michael ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
SV: [fpc-devel] fpc on AVR32
I have made a preliminary backend and RTL stub in branches/laksen/avr32new/ Some of the large problems is that the load instructions allow non-aligned loads in the ld.w forms. This proves to introduce many strange problems, and I don't have any debug equipment.

This proves to introduce many strange problems, and I don't have any debug equipment. Regards, Jeppe I bought JTAGICE mkII, it works nicely with Scientific Linux 6.2. The binaries from Fedora 12 and 13 work with Scientifc Linux. I will have no problem with debugging AVR32 code. What I find with AVR32 is that it makes nice compact code. I have written code for a cluster with a Micronas (ARM7TDMI) and AVR32UC3C 144 pins and found a major reduction in code size and code is a lot faster. That is running at the same speed. I run both at 48Mhz. I will look at your code, nice to know that I don't have to start from scratch. I don't really like eclipse, do you know if anyone is working on a plugin for codeblocks? I will have to learn the AVR32 assembler. I have coded automotive applications with the 100 pins and 144 pins devices AVR32UC3C but only in C with IAR. I have a very good knowledge of the processors. I wrote a lot of assembler with the AVR8 but never with the AVR32. At home I use gcc with eclipse since it is the only thing right now. Just so you know, I started with microprocessors in the early 70s, thus not a newbie with microprocessors. I will keep you posted of my progress.

I use it in combination with the AVR ONE! debug interface and the gnu tool chain. http://sourceforge.net/projects/mseide-msegui/ Martin ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
