Also you didn't specify the calls you're using to build u-boot and to run qemu. A good guide (a bit old): https://elinux.org/Virtual_Development_Board |

Edit: Didn't work. For the U-Boot build, I did like a million builds using mainline U-Boot (U-Boot 2019.10-rc3 as of the time of writing). Each time, I would do this: Code:
CROSS_COMPILE=~/arm-2014.05/bin/arm-none-linux-gnueabi- make ARCH=arm <name_of_defconfig> CROSS_COMPILE=~/OLDarm-2014.05/bin/arm-none-linux-gnueabi- make ARCH=arm -j8 Code:
$ ls ~/Downloads/u-boot-2019.10-rc3/configs/ | grep mx Building mainline for the Versatile and Versatile Express boards works, even when using the older GCC, and U-Boot actually boots, as illustrated in the link you attached. But not the i.MX6 configs. Every config I tried failed to boot (but compiled successfully) The only i.MX board which works is the i.MX25 board. But that's still too far from the Kindle, and the Kindle kernels won't boot on this board. Nor would the Kindle kernels boot on QEMU's i.MX6 boards when I tried booting them without U-Boot. As for booting in QEMU: I'm using a lot of different variations on this call: (please scroll right to view the whole line) Code:
$ qemu-system-arm -M {mcimx6ul-evk|sabrelite|mcimx7d-sabre}* -m 512M {-kernel} ~/Downloads/u-boot-2019.10-rc3/{u-boot.bin|u-boot|u-boot.imx|u-boot.img} -monitor stdio {-dtb ~/Downloads/u-boot-2019.10-rc3/u-boot.dtb**} {-append "console=ttymxc0"}
** If generated by the build. Last edited by WaseemAlkurdi; 09-20-2019 at 08:05 AM. |

Why are you not using the Amazon/Lab126 provided source of U-Boot? You can't (and shouldn't) assume that a vendor provided, modified, source package will build or work the same as the mainline source. |

When I can get any U-Boot at all to boot in QEMU as i.MX6, I'm sticking permanently to Lab126 sources because they have the Kindle-specific modifications. (like idme variables and the like, which is, after all, why I'm sticking to their sh*tty ten-year-old tree). Note that I have both trees side-by-side, and I'm ready to modify and build whichever tree you want me to. EDIT: This is what happens when I try to build Amazon's U-Boot for versatile as to test it in QEMU ... Code:

The poster in this StackExchange thread is trying to do exactly what we are doing here ... only they are doing it for the reMarkable Tablet instead. I'm following along.
It seems like a good idea to use a generic sabrelite kernel + Kindle rootfs kernel ... or is it? Has the Kindle's kernel tree deviated a lot from mainstream? In other words, do you think it's a good idea to try this? Edit: Surprise surprise! The U-Boot image which the poster has booted successfully in their QEMU instance didn't boot in mine. But is it really an issue with my compilation? I don't think so because even Ubuntu's packaged QEMU didn't boot that image. Last edited by WaseemAlkurdi; 09-22-2019 at 03:42 PM. |

I have been trying the same for a few weeks and figured that u-boot is dead-end.
The last example you provided booted though (Thanks) Code:

 I'm going to reproduce your steps. You seem to have used the rex board instead of wario, which I'm currently using. Perhaps that might explain something? As for U-Boot being a dead end, why have you come to that conclusion? In your example, didn't U-Boot boot at all? As far as I know, if there is a problem in the file you supplied with -bios, then the boot sequence should have stopped, instead of continuing. It doesn't really "skip" U-Boot just like that. Have you tried compiling mainline U-Boot (instead of Lab126 U-Boot) to see whether it boots under your setup of (host, QEMU version, cross-compiler toolchain)? Under my setup, the only i.MX board that boots in U-Boot is the imx25-pdk, and that happened with both mainline and Lab126 U-Boot. Edit: Have some karma! :-) Edit 2: If we bring up the Kindle OS without relying on U-Boot, then it would be good, but I feel that the presence of U-Boot is very important, because of the implementation of idme variables, which is necessary to boot without modifying the userland to skip the missing variables, and to provide a more complete emulation package overall. Edit 3 - Breaking news: I have booted the prebuilt kernel from the StackExchange thread above! The magic is in the kernel commandline. This explains why U-Boot didn't work ... it's because using -append with the magical option that fixes the kernel requires passing -kernel as well ... Edit 4: The magical option is console=ttymxc0!

I managed to run the i.MX kernel in QEMU ARM too. But still no word on U-Boot. I've contacted the QEMU mailing list, and they provided me with a possible patch, but how to apply it is a mystery (it's got ARM assembler code). And the booted kernel seems to be panicking very early on for some reason. Anyhow, U-Boot seems to be very far away unless QEMU is fixed up. I might post it up here if somebody's interested.

@smindux
https://lists.nongnu.org/archive/htm.../msg00837.html https://lists.nongnu.org/archive/htm.../msg00923.html These are the replies I got. I did the patches, but it seems I need to know ARM assembler to continue. Last edited by WaseemAlkurdi; 10-07-2019 at 09:06 AM. |

Meanwhile I managed to build u-boot that is provided by lab126 as per instructions in this previous post.
However as you might expect I could not boot it. The debugging example Philippe provided is great and very enlightening, yet I get very different output. Quote:
In addition to what Philippe suggested for enabling debugging on QEMU I enabled debugging in u-boot as well Code:
CFLAGS+= -DCONFIG_LOG -DDEBUG -DCONFIG_LOGLEVEL=8 -DCONFIG_LOG_CONSOLE -DCONFIG_MAX_LOG_LEVEL=8 Next step is either someone points out my stupidity or I attach gdb to QEMU and try my chances ... not very optimistic about this last one. As far as I understood the topic about idme - it is fluid enough to be able to set/modify it after kernel boot. Introductory ARM Assembly if you want to dive. |

CFLAGS is for enabling u-boot debugging and LOGLEVEL=8 should be quite verbose as per documentation. Maybe trying this setup for i386 just for verification is sound idea, but this is an exercise for another day. |
