Swapping partitions 1 and 2 in the partition table (code only, locations stay the same): results in Windows reading the FAT32 partition, camera reading FAT32 partition and not booting CHDK anymore until this change is reversed As long as you access your camera through USB, it should be transparent and you should have no problems.įor the record, if anyone has any ideas, here is what I've tried so far: There might be a workaround, but it involves a client-side modification and you might have to insert the SD card twice before getting access to the FAT32 partition and you will have to run the program again to get the camera to boot CHDK again.Įverything works fine on Linux, though, it's just that Windows is pedantic about it. I have carefully looked into this and there seems to be NO way of having a >4GB SDHC card boot CHDK on the camera AND be read by Windows. let's use the first partition on removable media and let's thwart any attempts at using the second partition in any way whatsoever. In the disk manager it'll show both(all) partitions, but it will refuse to read the FAT32 one (assuming the previously mentioned setup), as Microsoft thought. While it's OK for a camera to not care about several partitions on a memory card, a PC should be able to handle them ALL, since SD cards are really general-purpose devices. Now for the real drawback: Windows is about as stupid as the camera when it comes to reading the SD card's partition table. For *every* camera model, this code will have to be traced and modified all over again, so this currently only works on the S5 and (possibly) the A720, I haven't heard of anyone attempting to use that code on other models yet. The thing is, this is still platform-dependant code. Now I hooked the boot code so it would show the camera the FAT32 partition, so it doesn't know about the FAT16 partition after CHDK has loaded. create a small (32MB) FAT16 partition, bootable and with CHDK on it, create a second, large (~8GB) FAT32 partition for your pictures. An SD card is a normal block device, with a partition table and everything.
