Probably because
1) not that many people build with the primaries in the src tree (there are no dumps in svn, after all)
2) many distros (such as Debian on which I used to compile CHDK) use bash (or some other sufficiently extended shell) as /bin/sh by default

hi,

here is the port for the ixus40 (sd300) firmware 100k adapted for firmware 100j.  additionally it corrects the series-shooting bug (shooting series as well as bracketing now works).  setting iso < 58 results in whitescreen + poweroff (take care with the autoiso settings).

please add this to the trunk.

thanks,
fred.

p.s. works well in juciphox too.

tried to apply your patch to trunk. applying patch works, compiling for ixus40 100j fails though. maybe i did something wrong, please someone else confirm this.

Hello ppl!

I think it's time to put sd1100 into the trunk. I just merged the latest stuff and made another release:

SD1100/ixus 80 porting ....

A patch is attached there. I hope, this build is as stable as the previous. There was no crash report since then.

However, it's still missing the move_rec and sdhc_largedisk support. I hacked that but it still freezes in PLAY mode. It is in the patch but disabled in the build chain.

The greatest problem is, that the diskboot.bin file must be encoded to be bootable. So no hacker can contribute unless running qemu/gdb ... and it can't go to the automated build thing, too.

(Reminder to that prob: Problems dumping the SD1100IS/IXUS80IS |  Emulating Digicam with QEMU ... udumper2008)

So I wrote this little tool (included in patch):

Code: (c) [Select]
/*
 * make an image bootable for latest cams
 * (c) 2008 chr
 *
 * GPL v3+
 *
 * Why make things easy if complex sells better?
 */
#include <stdio.h>
#include <stddef.h>
#include <string.h>
#include <stdlib.h>
#include <errno.h>

unsigned char _chr_[8] = { 4,6,1,0,7,2,5,3 };

unsigned char dance(unsigned char allbest, int fudgey);

#define GHOST 0x400
#define BARNEY 0x00

int main(int whim, char **reyalp) {
FILE *jeff666, *jucifer;
unsigned char *ewavr;

if (whim != 3) {
printf("usage: <in file> <out file>\n");
exit(1);
}

jeff666  = fopen(reyalp[1], "r");
if (jeff666 == NULL) {
printf("Error open %s: %s\n", reyalp[1], strerror(errno));
exit(1);
}
jucifer = fopen(reyalp[2], "w+");
if (jucifer == NULL) {
printf("Error open %s: %s\n", reyalp[2], strerror(errno));
exit(1);
}
fputc(BARNEY, jucifer);
ewavr = malloc(GHOST);

int grand, hacki = 0;
int phox = fread(ewavr, 1, GHOST, jeff666);
while (phox > 0) {
for (grand=0; grand<phox; grand+=8) {
unsigned char fe50[8];
for (hacki=0; hacki<8; hacki++) {
// fe50[hacki] = dancingbits(ewavr[grand + _chr_[hacki]], grand+hacki);
fe50[_chr_[hacki]] = dance(ewavr[grand + hacki], grand+hacki);
}
fwrite(fe50, 1, 8, jucifer);
}
phox = fread(ewavr, 1, GHOST, jeff666);
}
fclose(jeff666);
fclose(jucifer);
free(ewavr);
exit(0);
}

unsigned char dance(unsigned char allbest, int fudgey) {
if ((fudgey % 3) !=0)
return allbest ^ 0xff;
if ((fudgey & 1) == 0)
return allbest ^ 0xa0;
return (allbest >> 4) | (allbest << 4);
}

Note: it's already reverted. Must not run 15 times ;)
TODO: include this somehow into the build chain.
