Ubuntu20.04 builds RISC-V and qemu environment
1. Preface risc-v is a very potential instruction set framework, and I have become very interested in it recently. Since I had very little knowledge in this area before, and the online tutorials were all just click-to-click, the installation process was extremely tortuous. . Fortunately, after accumulating and exploring step by step in the end, […]
qemu–use u-boot to load the kernel
In the previous article, we used qemu to start uboot. Now we test the process of booting the kernel under uboot. Test environment Host system: ubuntu 18.04 LTS Cross-compilation tool chain: arm-linux-gnueabi- uboot version: u-boot-2017.05-rc2 Kernel version: 4.4.76 Make sd card The previous kernel prompt was not found, so it stayed in uboot command line […]

Windows system uses QEMU to build ARM+Linux development environment
Cause Since many simulators currently on the market, such as Yeshen and NetEase MUMU, basically use the x86 architecture, although there is no problem running ARM programs, if you want to use gdb to debug ARM programs, you can It seems that I am unable to do what I want, and various problems arise one […]
GDB+ serial port debugging based on TQ2440 and Qemu (1)
Author Peng Donglin [email protected] Platform TQ2440 + Linux-4.10.17 Qemu(vexpress-ca9) + Linux-4.10.17 Overview The following is a brief introduction to using TQ2440 and Qemu to build a KGDB debugging environment. For TQ2440, KGDB + serial port debugging is used. For Qemu, it already provides a debugging interface. You only need to add relevant parameters when starting […]
Use Qemu to simulate vexpress-a9 (1) — Build a Linux kernel debugging environment

One is to use git to directly download the kernel code tree to facilitate […]
Use Qemu to simulate vexpress-a9 (3) — Implement u-boot to boot the Linux kernel
Environment introduction Win7 64 + Vmware 11 + ubuntu14.04 32 u-boot version: u-boot-2015-04 Linux kernel version: linux-3.16.y busybox version: 1_24_stable Cross-compilation tool chain: arm-linux-gnueabi- qemu version: stable-2.4 Overview The method I use here is to use network boot to start the Linux kernel. The specific methods are as follows: Enable Qemu’s network support function, start […]
Use QEMU to simulate running uboot to boot Linux from the SD card
Platform: Qemu + vexpress-a9 u-boot: u-boot-2019.10 Linux: linux-4.14.13 I have previously introduced using Qemu to simulate running uboot, and then booting linux from the network (using Qemu to simulate vexpress-a9 (3)—implementing u-boot to boot the Linux kernel). Next, we will introduce using Qemu to run uboot, and then store it in the virtual Load the […]
