At @ames sega mega drive red screen

[cubbox]

Ah the firmware dump I'm using is from a post @dcuk7 shared on page 4 of the custom firmware for sega flashback 2018 thread. I tried to compile the files into a single image with a package-file using something called afptool but the resulting .img wouldn't flash.

Android Tool looks like it might be the answer! dcuk7's firmware dump only has a parameter file and a bunch of .img files, no config .cfg unfortunately. Can I create one from the parameter file? It appears to have partition addresses and sizes in it towards the end:

CMDLINE:console=ttyS2,115200 androidboot.selinux=disabled earlyprintk init=/init initrd=0x62000000,0x00800000 root=/dev/rknand_rootfs rw rootwait mtdparts=rk29xxnand:0x00000800@0x00000800(misc),0x00004000@0x00001000(recovery),0x00000800@0x00005000(boot),0x00000800@0x00005800(resource),0x00002800@0x00006000(kernel),0x00007000@0x00008800(rootfs),0x0001E000@0x0000F800(rom),0x00004000@0x0002D800(emulator),-@0x00031800(data)

Although I'm not sure which value is the address and which is the size (if this even is what they refer to?!).

Thanks for your help!

Ok I'm definitely getting closer, managed to unpack one of the official ATGames firmware files which contained a config.cfg file. Imported that into Android Tool and have got the following setup:

I get some error creating image object if I click Run, not entirely sure why?

Turns out all it needed to complete successfully was unchecking the top row (parameter), I then flashed all the other partitions and it's working great again.



Thanks again for your help!!

Cool, so reflashing the device fixes the red screen issue!
Thank you for sharing your experience!
