I had spent far too much time trying to solve the Pi4 USB conundrum ( see https://rglinuxtech.com/?p=2922 ) but did recently find that the 5.14-rc kernels enabled the USB3 hub, although USB2 still failed to function. I then updated u-boot to the ‘latest’ version, and now everything (finally..) works as it should, again..: Updated u-boot to latest … Continue reading →
Recently acquired one of the Khadas VIM3-Pro arm64 SoCs, and was impressed with the level of documentation available.. Unfortunately – as is so often the case – this was all relentlessly Ubuntu-focussed, with a semi-proprietary kernel based on the 4.X kernel tree.. At least the U-Boot version was fairly recent, and appeared to support EFI etc.. The … Continue reading →
I have recently acquired an Odroid N2 (4GB) and managed – with some difficulty – to get it to run a ‘modern’ U-Boot, Kernel 5.6-rc2, with EFI support, and Fedora 31. This time, there were no clues from OpenSuse, and all the examples I found still used the ancient/custom Hardkernel u-boot and a kernel.img ‘blob. Fortunately, the … Continue reading →
When the Odroid C2 was first released way back in 2016, I spent ages trying to get it to function correctly with a mainstream kernel, and tested innumerable development versions of U-Boot, including functionality that was working OK at that time, but that – for some reason – then failed to be included in the ‘mainstream’ U-Boot.. … Continue reading →
Thanks to Heiner Kallweit, there is now a functional version of U-Boot for the Odroid C2, at https://github.com/hkallweit/u-boot .. I have installed it on my C2 (eMMC) and it works fine.. Nice to have a functioning > saveenv command, at last.. U-Boot 2017.01-rc3 (Jan 14 2017 – 02:22:15 -0800) odroid-c2 DRAM: 2 GiB MMC: meson_mmc: 0, meson_mmc: … Continue reading →
I recently obtained one of the newly-released (- to the ‘public’..) Pine64 ARM64 systems… My first reaction, was that it is a bit on the large side.. The board is over twice the size of the Odroid C2.. As usual, the ‘standard’ U-Boot was a heavily-customised old version, that only mounted Android-format Kernel ‘blob’s, but a hacked … Continue reading →
Thanks to an additional U-Boot patch from Carlo Caione, it is now possible to (partially) boot the mainline Kernel from U-Boot on an eMMC module, as well as from SDcard.. Patch details here: https://www.mail-archive.com/u-boot@lists.denx.de/msg213468.html => mmc info Device: <NULL> Manufacturer ID: 15 OEM: 100 Name: BGND3 Tran Speed: 52000000 Rd Block Len: 512 MMC version 5.0 High … Continue reading →
After the initial patches to provide basic U-Boot support for the C2, as mentioned in a previous article – there is now a further patch, to enable MMC support. Details at https://www.mail-archive.com/u-boot@lists.denx.de/msg212503.html I have applied this additional patch, and for SDcard-based systems, it works: U-Boot 2016.05-rc3 (May 14 2016 – 21:06:28 -0700) odroid-c2 aarch64-linux-gnu-gcc (GCC) 5.3.1 20160212 … Continue reading →
After some valuable info received from Brad (see comment on my earlier article, at http://rglinuxtech.com/?p=1723 ), I found the complete set of four patches for initial C2 U-Boot support, and applied these to the latest (May 9) GIT version of U-Boot.. Thanks are also due to Beniamino Galvani for producing these patches.. Detailed instruction on how to … Continue reading →
I discovered there was a later version (6) of the U-boot patch for the Odroid C2, and also – after more research – found the reason for the compile error… It turns out that the GIT version (May 5, 2016) of U-boot currently needs two patches.. The first one is to provide psci_system_reset for armv8, and details … Continue reading →
