In our implementation, all of them are covered in the eos_handle_* functions (which looks a bit different from other QEMU code, as they were ported from another emulator, back in the old days).Īn interrupt can be triggered whenever an external device does something interesting ( here's an example).Īssert: File. MMIO registers cover GPIOs, interrupt controller(s?), DMA controllers, communication with other CPU cores, image processing modules, I2C, SPI, UART and so on. MMIO registers and hardware interrupts are the only external interfaces of this CPU to other devices, as far as I could tell. However, all the functionality of the "guest" program (here, the firmware) can be changed from MMIO registers and/or triggering an interrupt (you only need the former method here). The place where the code path should be changed is not the same place where it locks up (that's a bit tricky). ![]() You'll have to configure the emulator in a way that "forces" the boot code to pick the FROMUTILITY path, instead of the System adjustment menu. Additionally, -singlestep is useful for getting correct program counters in the io logs (otherwise, you'll often get the start of a small function, rather than the exact address where the MMIO access happens). You can also use -d io (or -d exec,int,io) to get some more info about what happens, and you may find it helpful following the code branches in IDA (e.g. Next step is to prevent the adjustment menu from coming up (and launch the main firmware instead). In the meantime if anyone can offer some suggestions, ive uploaded exec,int output and a function trace, plus the profile details to Ill happily admit though that at this point im fairly lost, but ill do some reading to try and keep moving.

Next step I guess is to attach gdb and try and figure out whats actually going on?Īlso to figure out what the hell im doing.ĮDIT2: OK So it helps if im running qemu using the patches in the current branch, not some old stuff. Lo an behold there was some execution and what looks like now idle output on the console. I tried to figure out the offset from the ROM, and came up with 0xF8008000 based on the above patch to ROM1. But honestly, I only have a small idea of what im doing here, just an honest interest in figuring it out.Īny suggestions from the almightly userbase? I set it to FF801000 which is noted above as being the bootloader position, and got some minor output suggesting some code was executed, but it stalled after a few shifts, so im thinking im in the wrong boot position. a term used for a beginners camera, like a Canon Rebel (xxxD in Europe. I dont actually have any clue what the register address in the source is supposed to be targeting. When you go to the Dragonframe website you will find a list of digital stills. Did it twice and compared, good dumps I assume as they were identical.Ĭompiled QEMU and added Machine Rego in eos.c for the 1300D. Right im resurrecting this only slightly cooled off thread because its right what I needĭumped ROM - Success. I've used this one ( ) but i guess it's only for cameras where ML is already installed?
