qemu don't start *.abs firmware files

[David Martins]

Hello Devs,

I'm here to report this bug/issue because i'm using Win64 Qemu but i can't start a *.abs firmware at normally this firmware is based in Linux Kernel and this type of firmware is made for STB Receivers,

So this is all information i provide to get support.

When I use readelf it says files isn't an ELF file, so i can't run it like a kernel (Bootloader,Maincode, and etc. )

so this is the cmd output when i use qemu Win64 (I don't whant to use linux to do the emulation about this *.abs extension firmware so please help me for win64 version from Qemu)

CMD OUTPUT:

 C:\Program Files\qemu>qemu-system-mips.exe -machine mips -cpu mips32r6-generic -drive file=C:\30080.bin,index=0,media=disk,format=raw

qemu-system-mips.exe: warning: could not load MIPS bios 'mips_bios.bin'

I also tried a lot of diferents qemu-system... and a lot of diferent configs like -machine -cpu -kernel -driver root= -PFLASH and etc... and nothing hapenned

How can i reproduce this issue ?
Reply:.

Donwload *.abs firmware in amikoreceiver.com (only *.abs) and download AliDekompressor in http://www.satedu.cba.pl/

Direct tools:

FirmwareDecrypter_v8.9.zip :

http://www.satedu.cba.pl/index.php?action=downloadfile&filename=FirmwareDecrypter_v8.9.zip&directory=Test%20Folder&

Ali__tools_Console_v4.0__CRC_FIXER.rar :

http://www.satedu.cba.pl/index.php?action=downloadfile&filename=Ali__tools_Console_v4.0__CRC_FIXER.rar&directory=Test%20Folder&

so if Qemu can explain how can i fix this issue this can be highly helpfull.

With my best regards,

As far as I understand the original description, this was about running an arbitrary firmware in QEMU that has been written for a board that we do not support in QEMU? This can not work. A machine consists of a CPU and various devices that are on board, so you can only run the software that has been written for the CPU and the corresponding devices. If I've got you right, you want to run some software for a board that we do not model in QEMU, so it just can't work since the required devices are not emulated. Thus I'm closing this as "Invalid" now ... unless I've misunderstood your description, then please complain and we can open the ticket again.

Comment #1 from Thomas is correct, this MIPS machine is not modelled.
