Hi all,

I'm having some trouble with a wisp628 I just built. Firstly, I didn't 
have any '628s handy, so I decided to use an F88 I had nearby. To do 
this I had to swap some pins on the hardware since the F88 uses 
different USART pins. Specifically RB1 becomes RB2, RB2 becomes RB5, and 
RB5 becomes RB1. Then I tried to modify the firmware to use the new pins 
(and address some differences between the chips like disabling A/D), but 
I can't get jal (0.4.62) to compile it. No matter what commandline 
options I try, I always get:

jal 0.4.62 (GCC 3.3)
 >  error: code too large 3374 (2047 available)

I ended up disassembling and editing the .hex that Wouter provides 
(replacing the bits in accesses to PORTB and the PORTB and TRISB shadow 
registers that JAL uses, plus adding some stuff). It works fine for all 
the older chips, but I want to use it to program the 18F4550. This is 
again unsupported (needs a new programming algorithm). Fortunately, Rob 
Hamerling already has his own modified version 
(http://www.robh.nl/picsoft.php) plus PC-side software, but he only 
provides a jal file which I can't compile.

It seems the problems with JAL are that it puts in way too many bank 
switching statements (compared to the disasm'ed version from Wouter). 
Maybe he used a different version of JAL? If so, which version works?

Any help would be appreciated. I hope I can soon get a stab at the new 
USB PICs :-)
