From a30abb1b6bb66d1caf08c331805163e6fef6f2a1 Mon Sep 17 00:00:00 2001 From: DENG Qingfang Date: Tue, 14 Jan 2020 22:22:59 +0800 Subject: ipq40xx: add support for MobiPromo CM520-79F MobiPromo CM520-79F is an AC1300 dual band router based on IPQ4019 Specification: SoC/Wireless: QCA IPQ4019 RAM: 512MiB Flash: 128MiB SLC NAND Ethernet PHY: QCA8075 Ethernet ports: 1x WAN, 2x LAN LEDs: 7 LEDs 2 (USB, CAN) are GPIO other 5 (2.4G, 5G, LAN1, LAN2, WAN) are connected to a shift register Button: Reset Flash instruction: Disassemble the router, connect UART pins like this: GND TX RX [x x . . x .] [. . . . . .] (QCA8075 and IPQ4019 below) Baud-rate: 115200 Set up TFTP server: IP 192.168.1.188/24 Power on the router and interrupt the booting with UART console env backup (in case you want to go back to stock and need it there): printenv (Copy the output to somewhere save) Set bootenv: setenv set_ubi 'set mtdids nand0=nand0; set mtdparts mtdparts=nand0:0x7480000@0xb80000(fs); ubi part fs' setenv bootkernel 'ubi read 0x84000000 kernel; bootm 0x84000000#config@1' setenv cm520_boot 'run set_ubi; run bootkernel' setenv bootcmd 'run cm520_boot' setenv bootargs saveenv Boot initramfs from TFTP: tftpboot openwrt-ipq40xx-generic-mobipromo_cm520-79f-initramfs-fit-zImage.itb bootm After initramfs image is booted, backup rootfs partition in case of reverting to stock image cat /dev/mtd12 > /tmp/mtd12.bin Then fetch it via SCP Upload nand-factory.ubi to /tmp via SCP, then run mtd erase rootfs mtd write /tmp/*nand-factory.ubi rootfs reboot To revert to stock image, restore default bootenv in uboot UART console setenv bootcmd 'bootipq' printenv use the saved dump you did back when you installed OpenWrt to verify that there are no other differences from back in the day. saveenv upload the backed up mtd12.bin and run tftpboot mtd12.bin nand erase 0xb80000 0x7480000 nand write 0x84000000 0xb80000 0x7480000 The BOOTCONFIG may have been configured to boot from alternate partition (rootfs_1) instead In case of this, set it back to rootfs: cd /tmp cat /dev/mtd7 > mtd7.bin echo -ne '\x0b' | dd of=mtd7.bin conv=notrunc bs=1 count=1 seek=4 for i in 28 48 68 108; do dd if=/dev/zero of=mtd7.bin conv=notrunc bs=1 count=1 seek=$i done mtd write mtd7.bin BOOTCONFIG mtd write mtd7.bin BOOTCONFIG1 Signed-off-by: DENG Qingfang [renamed volume to ubi to support autoboot, as per David Lam's test in PR#2432] Signed-off-by: Christian Lamparter --- package/firmware/ipq-wifi/Makefile | 2 ++ .../firmware/ipq-wifi/board-mobipromo_cm520-79f.qca4019 | Bin 0 -> 24308 bytes 2 files changed, 2 insertions(+) create mode 100644 package/firmware/ipq-wifi/board-mobipromo_cm520-79f.qca4019 (limited to 'package/firmware') diff --git a/package/firmware/ipq-wifi/Makefile b/package/firmware/ipq-wifi/Makefile index 12e000bac8..f767d49294 100644 --- a/package/firmware/ipq-wifi/Makefile +++ b/package/firmware/ipq-wifi/Makefile @@ -33,6 +33,7 @@ ALLWIFIBOARDS:= \ engenius_emd1 \ ezviz_cs-w3-wd1200g-eup \ linksys_ea8300 \ + mobipromo_cm520-79f \ qxwlan_e2600ac ALLWIFIPACKAGES:=$(foreach BOARD,$(ALLWIFIBOARDS),ipq-wifi-$(BOARD)) @@ -102,6 +103,7 @@ $(eval $(call generate-ipq-wifi-package,engenius_eap2200,EnGenius EAP2200)) $(eval $(call generate-ipq-wifi-package,engenius_emd1,EnGenius EMD1)) $(eval $(call generate-ipq-wifi-package,ezviz_cs-w3-wd1200g-eup,EZVIZ CS-W3-WD1200G EUP)) $(eval $(call generate-ipq-wifi-package,linksys_ea8300,Linksys EA8300)) +$(eval $(call generate-ipq-wifi-package,mobipromo_cm520-79f,MobiPromo CM520-79F)) $(eval $(call generate-ipq-wifi-package,qxwlan_e2600ac,Qxwlan E2600AC)) $(foreach PACKAGE,$(ALLWIFIPACKAGES),$(eval $(call BuildPackage,$(PACKAGE)))) diff --git a/package/firmware/ipq-wifi/board-mobipromo_cm520-79f.qca4019 b/package/firmware/ipq-wifi/board-mobipromo_cm520-79f.qca4019 new file mode 100644 index 0000000000..d717af12fe Binary files /dev/null and b/package/firmware/ipq-wifi/board-mobipromo_cm520-79f.qca4019 differ -- cgit v1.2.3
