From dfa0a38d1f4d5bbac768569e3769ae4438a57e73 Mon Sep 17 00:00:00 2001 From: Daniel Golle Date: Sat, 27 Feb 2021 14:17:09 +0000 Subject: [PATCH] mediatek: rework support for BananaPi BPi-R64 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit **What's new** * Bring support for the Bananapi BPi-R64 to the level desirable for a nice hackable routerboard. * Use ARM Trusted Firmware A from source. (goodbye binary preloader) * Use Das U-Boot from source. (see previous commit) * Assemble SD-card image using OpenWrt image-commands. (no gen_sd_cruz_foo.sh added, this is not Raspbian) * Updated kernel options to support root filesystem. * Updated DTS to match OpenWrt LAN ports, known LEDs, buttons, ... * Detect root device, handle sysupgrade, config restore, ... * Wire up (known) LEDs and buttons in OpenWrt-fashion. * Build one set of images from SD-card and eMMC. * Hopefully provide a good example of how things can be done right from scratch. **Installation and images** * Have an empty SD-card at hand * Write stuff to the card, as root (card device is /dev/mmcblkX) - write header, gpt, bl2, atf, u-boot and recovery kernel: `cat *bpi-r64-boot-sdcard.img *bpi-r64-initramfs-recovery.fit > /dev/mmcblkX` - rescan partitions: `blockdev --rereadpt /dev/mmcblkX` - write main system to production partition: `cat *bpi-r64-squashfs-sysupgrade.fit > /dev/mmcblkXp5` * Installation to eMMC works using SD-card bootloader via TFTP When running OpenWrt of SD-card, issue this to trigger installation to eMMC: `fw_setenv bootcmd run emmc_init` Be prepared to serve the content of bin/targets/mediatek/mt7622 on TFTP server address 192.168.1.254. **What's missing** * The red LED is always on, probably a hardware bug. * AHCI (probably needs DTS changes) * Ship SD-card image ready with every needed for eMMC install. * The eMMC has a second, currently unused boot partition. This would be ideal to store the WiFi EEPROM and Ethernet MAC address(es). @sinovoip ideas? Thanks to Thomas Hühn @thuehn for providing the hardware!
