目前树莓派的 GPU bootloader 仍未开源,只以二进制形式发布,本项目 bottom 路径下提供了从raspberrypi/firmware官方仓库中提取了 bootcode.bin 和 start.elf,直接复制到 SD 卡根目录下即可。
需要配置启动选项和顺序,可以通过Raspberry Pi Imager(PC上的Image工具)或者命令行Configuration GUI等方式,具体可以参阅这个链接。对于RaspberryPi Imager来说,用于配置Bootloader的入口参阅如下图片: 图7-用Raspberry Pi Imager配置树莓派4B的Bootloader 树莓派4B启动日志和LED状态有哪些? 树莓派4B的启动日志,可以通过HDMI...
Raspberry Pi 3 TheRaspberry Pi3 was released in early March 2016, shortly before the release of Ubuntu 16.04 (Xenial) LTS, but too short to have proper support. It is possible to run Xenial's kernel and a full Ubuntu installation, but it requires replacing the firmware, bootloader and some...
Waveshare 电子纸显示器与树莓派之前通过 SPI 进行通信。因此，需要在 Raspberry Pi 上启用 SPI。

Yesterday, we introduced the first of two new boot modes which have now been added to the Raspberry Pi 3. Today, we introduce an even more exciting addition: network booting a Raspberry Pi with no SD card. Again, rather than go through a description of the boot mode here, we’ve writte...
这里arduino指其所用芯片：ATMEGA328P，自己做PCB需要烧写bootloader；树莓派：Raspberry Pi 3b。
Insert the SD card/plug the USB drive and power up your Raspberry Pi. You should see a multicoloured screen (which indicates that the CPU-embedded bootloader is reading the data from the SD/USB partition) and then the Raspberry Pi black and white logo once the UEFI firmware is ready. ...
未启动 Raspberry Pi 4B bootloader EEPROM 求助答疑 Wobbo (Wobbo) 2021 年10 月 8 日 11:33 1 我已经执行了 rpi-eeprom 固件更新。 从版本 2021-04-29 到 2021-07-07。 不幸的是,FydeOS 不再启动。 我试过好几个了。 不同的树莓派 4B、不同的线缆、不同的屏幕、不同版本的 FydeOS(测试版和最新...
