From: Sven Eckelmann Date: Mon, 23 Nov 2020 12:41:34 +0000 (+0100) Subject: ath79: Add support for OpenMesh OM2P v1 X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=8143709c90c3aa0a84e14cf4a9dfbcb365b0d966;p=openwrt%2Fstaging%2Faparcar.git ath79: Add support for OpenMesh OM2P v1 Device specifications: ====================== * Qualcomm/Atheros AR7240 rev 2 * 350/350/175 MHz (CPU/DDR/AHB) * 32 MB of RAM * 16 MB of SPI NOR flash - 2x 7 MB available; but one of the 7 MB regions is the recovery image * 2x 10/100 Mbps Ethernet * 1T1R 2.4 GHz Wi-Fi * 6x GPIO-LEDs (3x wifi, 2x ethernet, 1x power) * 1x GPIO-button (reset) * external h/w watchdog (enabled by default) * TTL pins are on board (arrow points to VCC, then follows: GND, TX, RX) * 2x fast ethernet - eth0 + 18-24V passive POE (mode B) + used as WAN interface - eth1 + builtin switch port 4 + used as LAN interface * 12-24V 1A DC * external antenna The device itself requires the mtdparts from the uboot arguments to properly boot the flashed image and to support dual-boot (primary + recovery image). Unfortunately, the name of the mtd device in mtdparts is still using the legacy name "ar7240-nor0" which must be supplied using the Linux-specfic DT parameter linux,mtd-name to overwrite the generic name "spi0.0". Flashing instructions: ====================== Various methods can be used to install the actual image on the flash. Two easy ones are: ap51-flash ---------- The tool ap51-flash (https://github.com/ap51-flash/ap51-flash) should be used to transfer the image to the u-boot when the device boots up. initramfs from TFTP ------------------- The serial console must be used to access the u-boot shell during bootup. It can then be used to first boot up the initramfs image from a TFTP server (here with the IP 192.168.1.21): setenv serverip 192.168.1.21 setenv ipaddr 192.168.1.1 tftpboot 0c00000 .bin && bootm $fileaddr The actual sysupgrade image can then be transferred (on the LAN port) to the device via scp .bin root@192.168.1.1:/tmp/ On the device, the sysupgrade must then be started using sysupgrade -n /tmp/.bin Signed-off-by: Sven Eckelmann --- diff --git a/package/boot/uboot-envtools/files/ath79 b/package/boot/uboot-envtools/files/ath79 index b01a713705..7aa992e458 100644 --- a/package/boot/uboot-envtools/files/ath79 +++ b/package/boot/uboot-envtools/files/ath79 @@ -103,6 +103,7 @@ netgear,wndr4300tn|\ netgear,wndr4300sw) ubootenv_add_uci_config "/dev/mtd1" "0x0" "0x40000" "0x20000" ;;
