I've been meaning to try out running Linux and Windows virtual machines on my x86 MacBook Pro using qemu . I've been using Parallels for several years. Parallels is a nice application and works well but I'm always getting bugged to purchase upgrades. Parallels provides free updates on minor version upgrades only, say 13.0 to 13.1. With so many prompts to purchase upgrades it feels like Parallels could release a bit more minor versions and a bit fewer major versions. Rather than just purchase an upgrade to Parallels I figured I'd try out qemu via the UTM application . UTM wraps qemu with a helpful gui and comes as a packages Mac application. And UTM supports both x86 and M1 systems (as qemu also supports these systems). Creating an Ubuntu VM with UTM didn't go as smoothly as with VirtualBox or Parallels but it was the settings I chose that messed me up. Here are two things I ran into when installing Ubuntu on UTM. #1. Configure the qemu instance to use a 'Display...

I've been a big fan of crosstool-ng ever since I found out that Dan Kegal's crosstool scripts  idea was being continued. I picked up one of these boards, an Olimex STM32-H103 , because I'm putting together a custom PCB with an STM32F103 on it and didn't want to be bringing up the toolchain at the same time as debugging the hardware. Starting with this board means starting with a known working STM32F103 board. Steps - Install 'gcc-multilib' package. If you don't have this you'll get some odd errors when building the toolchain such as: [INFO ] ================================================================= [INFO ] Installing binutils for host [INFO ] Installing binutils for host: done in 142.17s (at 11:46) [INFO ] ================================================================= [INFO ] Installing pass-1 core C compiler [ERROR] checking dynamic linker characteristics... checking whether getchar_unlocked is declared... configure: er...
