From 4943afd7818f56053231a5a7ae90e55da44f1f08 Mon Sep 17 00:00:00 2001 From: Chris Blake Date: Sat, 10 Mar 2018 10:59:18 +0100 Subject: ipq40xx: add Cisco Meraki MR33 Support This patch adds support for Cisco Meraki MR33 hardware highlights: SOC: IPQ4029 Quad-Core ARMv7 Processor rev 5 (v7l) Cortex-A7 DRAM: 256 MiB DDR3L-1600 @ 627 MHz Micron MT41K128M16JT-125IT NAND: 128 MiB SLC NAND Spansion S34ML01G200TFV00 (106 MiB usable) ETH: Qualcomm Atheros AR8035 Gigabit PHY (1 x LAN/WAN) + PoE WLAN1: QCA9887 (168c:0050) PCIe 1x1:1 802.11abgn ac Dualband VHT80 WLAN2: Qualcomm Atheros QCA4029 2.4GHz 802.11bgn 2:2x2 WLAN3: Qualcomm Atheros QCA4029 5GHz 802.11a/n/ac 2:2x2 VHT80 LEDS: 1 x Programmable RGB+White Status LED (driven by Ti LP5562 on i2c-1) 1 x Orange LED Fault Indicator (shared with LP5562) 2 x LAN Activity / Speed LEDs (On the RJ45 Port) BUTTON: one Reset button MISC: Bluetooth LE Ti cc2650 PG2.3 4x4mm - BL_CONFIG at 0x0001FFD8 AT24C64 8KiB EEPROM Kensington Lock Serial: WARNING: The serial port needs a TTL/RS-232 3V3 level converter! The Serial setting is 115200-8-N-1. The board has a populated 1x4 0.1" header with half-height/low profile pins. The pinout is: VCC (little white arrow), RX, TX, GND. Flashing needs a serial adaptor, as well as patched ubootwrite utility (needs Little-Endian support). And a modified u-boot (enabled Ethernet). Meraki's original u-boot source can be found in: Add images to do an installation via bootloader: 0. open up the MR33 and connect the serial console. 1. start the 2nd stage bootloader transfer from client pc: # ubootwrite.py --write=mr33-uboot.bin (The ubootwrite tool will interrupt the boot-process and hence it needs to listen for cues. If the connection is bad (due to the low-profile pins), the tool can fail multiple times and in weird ways. If you are not sure, just use a terminal program and see what the device is doing there. 2. power on the MR33 (with ethernet + serial cables attached) Warning: Make sure you do this in a private LAN that has no connection to the internet. - let it upload the u-boot this can take 250-300 seconds - 3. use a tftp client (in binary mode!) on your PC to upload the sysupgrade.bin (the u-boot is listening on 192.168.1.1) # tftp 192.168.1.1 binary put openwrt-ipq40xx-meraki_mr33-squashfs-sysupgrade.bin 4. wait for it to reboot 5. connect to your MR33 via ssh on 192.168.1.1 For more detailed instructions, please take a look at the: "Flashing Instructions for the MR33" PDF. This can be found on the wiki: (A link to the mr33-uboot.bin + the modified ubootwrite is also there) Thanks to Jerome C. for sending an MR33 to Chris.
