Pinout is 0 - 3V3 (don't connect) 1 - RX 2 - TX 3 - GND Console is 115200 8N1. Boot ---- 1. Connect to the serial console and connect power. 2. Double-press ESC when prompted 3. Set the fdt address $ fdt addr $(fdtcontroladdr) 4. Remove the signature node from the control FDT $ fdt rm /signature 5. Transfer and boot the OpenWrt initramfs image to the device. Make sure to name the file C0A80114.img and have it reachable at 192.168.1.1/24 $ tftpboot; bootm Installation ------------ 1. Connect to the booted device at 192.168.1.20 using username/password "ubnt". 2. Update the bootloader environment. $ fw_setenv devmode TRUE $ fw_setenv boot_openwrt "fdt addr \$(fdtcontroladdr); fdt rm /signature; bootubnt" $ fw_setenv bootcmd "run boot_openwrt" 3. Transfer the OpenWrt sysupgrade image to the device using SCP. 4. Check the mtd partition number for bs / kernel0 / kernel1 $ cat /proc/mtd 5. Set the bootselect flag to boot from kernel0 $ dd if=/dev/zero bs=1 count=1 of=/dev/mtdblock4 6. Write the OpenWrt sysupgrade image to both kernel0 as well as kernel1 $ dd if=openwrt.bin of=/dev/mtdblock6 $ dd if=openwrt.bin of=/dev/mtdblock7 7. Reboot the device. It should boot into OpenWrt. Below are the original installation instructions prior to the discovery of "devmode=TRUE". They are not required for installation and are documentation only. The bootloader employs signature verification on the FIT image configurations. This way, booting unauthorized image without patching the bootloader is not possible. Manually configuring the bootcmd in the U-Boot envronment won't work, as this is restored to the default value if modified. The bootloader is made up of three different parts. 1. The SPL performing early board initialization and providing a XModem recovery in case the PBL is missing 2. The PBL being the primary U-Boot application and containing the control FDT. It is LZMA packed with a uImage header. 3. A Ubiquiti standalone U-Boot application providing the main boot routine as well as their recovery mechanism. In a perfect world, we would only replace the PBL, as the SPL does not perform checks on the PBLs integrity. However, as the PBL is in the same eraseblock as the SPL, we need to at least rewrite both. The bootloader will only verify integrity in case it has a "signature" node in it's control device-tree. Renaming the signature node to something else will prevent this from happening. Warning: These instructions are based on the firmware intially shipped with the device and potentially brick your device in a way it can only be recovered using a SPI flasher. Only (!) proceed if you understand this! 1. Extract the bootloader from the U-Boot partition using the OpenWrt initramfs image. 2. Split the bootloader into it's 3 components: $ dd if=bootloader.bin of=spl.bin bs=1 skip=0 count=45056 $ dd if=bootloader.bin of=pbl.uimage bs=1 skip=45056 count=143360 $ dd if=bootloader.bin of=ubnt.uimage bs=1 skip=188416 3. Strip the uImage header from the PBL $ dd if=pbl.uimage of=pbl.lzma bs=64 skip=1 4. Decompress the PBL $ lzma -d pbl.lzma --single-stream The decompressed PBL sha256sum should be d8b406c65240d260cf15be5f97f40c1d6d1b6e61ec3abed37bb841c90fcc1235 5. Open the decompressed PBL using your favorite hexeditor. Locate the control FDT at offset 0x4CED0 (0xD00DFEED). At offset 0x4D5BC, the label for the signature node is located. Rename the "signature" string at this offset to "signaturr". The patched PBL sha256sum should be d028e374cdb40ba44b6e3cef2e4e8a8c16a3b85eb15d9544d24fdd10eed64c97 6. Compress the patched PBL $ lzma -z pbl --lzma1=dict=67108864 The resulting pbl.lzma file should have the sha256sum 7ae6118928fa0d0b3fe4ff81abd80ecfd9ba2944cb0f0a462b6ae65913088b42 7. Create the PBL uimage $ SOURCE_DATE_EPOCH=1607909492 mkimage -A mips -O u-boot -C lzma -n "U-Boot 2018.03 [UniFi,v1.1.40.71]" -a 84000000 -e 84000000 -T firmware -d pbl.lzma patched_pbl.uimage The resulting patched_pbl.uimage should have the sha256sum b90d7fa2dcc6814180d3943530d8d6b0d6a03636113c94e99af34f196d3cf2ce 8. Reassemble the complete bootloader $ dd if=patched_pbl.uimage of=aligned_pbl.uimage bs=143360 count=1 conv=sync $ cat spl.bin > patched_uboot.bin $ cat aligned_pbl.uimage >> patched_uboot.bin $ cat ubnt.uimage >> patched_uboot.bin The resulting patched_uboot.bin should have the sha256sum 3e1186f33b88a525687285c2a8b22e8786787b31d4648b8eee66c672222aa76b 9. Transfer your patched bootloader to the device. Also install the kmod-mtd-rw package using opkg and load it. $ insmod mtd-rw.ko i_want_a_brick=1 Write the patched bootloader to mtd0 $ mtd write patched_uboot.bin u-boot 10. Erase the kernel1 partition, as the bootloader might otherwise decide to boot from there. $ mtd erase kernel1 11. Transfer the OpenWrt sysupgrade image to the device and install using sysupgrade.

* ramips: remove model name from LED labelsAdrian Schmutzler2020-10-021-2/+2
| | | | | | | | | | | | | | | | | Like in the previous patch for ath79 target, this will remove the "devicename" from LED labels in ramips as well. The devicename is removed in DTS files and 01_leds, consolidation of definitions into DTSI files is done where (easily) possible, and migration scripts are updated. For the latter, all existing definitions were actually just devicename migrations anyway. Therefore, those are removed and a common migration file is created in target base-files. This is actually another example of how the devicename removal makes things easier. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
* ramips: move dts-v1 statement to top-level DTSI filesAdrian Schmutzler2020-09-251-1/+0
| | | | | | | | | | | | | | | | | The "/dts-v1/;" identifier is supposed to be present once at the top of a device tree file after the includes have been processed. In ramips, we therefore requested to have in the DTS files so far, and omit it in the DTSI files. However, essentially the syntax of the parent mtxxxx/rtxxxx DTSI files already determines the DTS version, so putting it into the DTS files is just a useless repetition. Consequently, this patch puts the dts-v1 statement into the top-level SoC-based DTSI files, and removes all other occurences. Since the dts-v1 statement needs to be before any other definitions, this also moves the includes accordingly where necessary. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>

Hardware -------- SoC: MediaTek MT7621AT WiFi: MediaTek MT7603 bgn 2T2R MediaTek MT7615 ac 4T4R Flash: 32M SPI (Macronix MX25L25635F) RAM: 128M DDR3 (Winbond W631GG6KB) LED: Dome (Blue / White) BTN: Reset Installation ------------ These instructions were written for firmware version v3.9.27. Downgrade if necessary. 1. Copy the OpenWrt sysupgrade image to the devices /tmp folder via scp. On factory defaults, user and password is "ubnt" at 192.168.1.20/24. 2. Write the bootselect flag. Otherwise, the device might boot from the wrong partition. Verify the mtd partition used in the command below is the one labled "bs" in /proc/mtd (as this might change in the future). > dd if=/dev/zero bs=1 count=1 of=/dev/mtd4 3. Write the OpenWrt sysupgrade to the mtd partitions labled "kernel0" and "kernel1". > dd if=/tmp/openwrt-sysupgrade.bin of=/dev/mtdblock6 > dd if=/tmp/openwrt-sysupgrade.bin of=/dev/mtdblock7 4. Reboot or powercycle the device. Signed-off-by: David Bauer <mail@david-bauer.net>
