+# Acer Connect Vero W6m
+
+<img src="connect_vero_w6m_case.jpg" alt="Acer Connect Vero W6m" width=400 padding=10>
+
+## Overview
+
+The Acer Connect Vero W6m is a compact WiFi 6/6E router platform based
+on the MediaTek MT7986A SoC.  In Infix it is supported as an eMMC-based
+target that reuses the factory secure boot chain while replacing the
+system partitions with an Infix installation.
+
+The Acer Connect Vero W6m is based on the same MT7986a SoC as the
+BPI-R3, with tri-band WiFi (2.4 GHz + 5 GHz + 6 GHz) using a PCIe
+MT7916 module and the SoC's built-in MT7976 DBDC radio.
+
+## Default WiFi Layout
+
+The factory configuration on this branch enables all three radios in AP
+mode and bridges them into the default LAN bridge `br0`:
+
+- `radio0` / `wifi0-ap`: 2.4 GHz, SSID `Infix`
+- `radio1` / `wifi1-ap`: 6 GHz, SSID `Infix6G`
+- `radio2` / `wifi2-ap`: 5 GHz, SSID `Infix5G`
+
+6 GHz operation is enabled in the MT7915e driver configuration, and all
+three APs use the same default passphrase `infixinfix` from the factory
+configuration.
+
+Secure boot is enabled on this device, so the factory bootloader
+(partitions 1-4: bl2, u-boot-env, factory, fip) must not be modified.
+Infix is installed by replacing partitions 5+ while keeping the
+factory bootloader intact.  The stock U-Boot chainloads the Infix
+U-Boot from the first partition after fip.
+
+## Prerequisites
+
+- Serial console access (115200 8N1) — required to interrupt U-Boot.
+  Disassembly is needed to reach the UART header.  See the [OpenWrt
+  Vero W6m page][vero-openwrt] for details.
+- TFTP server on the local network with `u-boot.bin` for the initial
+  RAM boot.
+- SSH access from the running Infix system to a host that stores
+  `infix-vero-w-emmc.img`.
+- Ethernet cable connected between the PC and the Vero Internet/WAN
+  port.
+- DHCP server running on the PC, serving addresses on that link during
+  installation.
+- **Save the MAC addresses** from the stock U-Boot environment before
+  installing.  Interrupt autoboot and run `printenv` to note down:
+  `2gMAC`, `5gMAC`, `6gMAC`, `LANMAC`, and `WANMAC`.
+
+## Required Files
+
+Prepare these files on a host reachable from the Vero:
+
+1. **Infix Vero image:**
+   - [infix-vero-w-emmc.img][1] (Complete system image)
+2. **eMMC bootloader** (extracted from):
+   - [bpi-r3-emmc-boot-2025.01-latest.tar.gz][2]
+   - Extract `u-boot.bin` from the tarball to your TFTP server
+
+## Installing Infix
+
+Connect the PC directly to the Vero Internet/WAN port before starting
+the installation.  The PC should provide DHCP service on that link so
+the stock U-Boot and the temporary Infix system can reach the TFTP/SSH
+host.
+
+1. **RAM-load Infix U-Boot** from the stock U-Boot serial console
+   (hit any key to stop autoboot):
+
+   ```
+   setenv serverip <TFTP_SERVER_IP>
+   setenv ipaddr <VERO_IP>
+   setenv bootmenu_default 7
+   tftpboot 0x46000000 u-boot.bin
+   go 0x46000000
+   ```
+
+   `serverip` must point to your TFTP server and `ipaddr` must be a free
+   address for the Vero on the same subnet.  `bootmenu_default 7`
+   bypasses secure boot verification.  The Infix U-Boot will
+   automatically netboot the Infix system.
+
+2. **From running Infix**, stream the image directly to eMMC:
+
+   ```bash
+   ssh <USER>@<HOST> "dd if=/path/to/infix-vero-w-emmc.img bs=512 skip=17408 status=none" | \
+   dd of=/dev/mmcblk0 bs=512 seek=17408 conv=fsync
+   sync
+   ```
+
+   This writes only the Infix partitions (starting after fip at sector
+   17408), leaving the factory bootloader and calibration data intact.
+   Do not interrupt the transfer; if it fails, rerun the command from
+   the beginning.
+
+3. **Update the GPT** to replace stock partitions 5+ with the Infix
+   layout:
+
+   ```bash
+   sudo sgdisk --zap-all /dev/mmcblk0
+   sudo sgdisk -a 1 \
+       -n2:8192:9215      -c2:u-boot-env  \
+       -n3:9216:13311     -c3:factory      \
+       -n4:13312:17407    -c4:fip          \
+       -n5:17408:+32M     -c5:infix-uboot \
+       -n6:0:+8M          -c6:aux         \
+       -n7:0:+250M        -c7:primary     \
+       -n8:0:+250M        -c8:secondary   \
+       -n9:0:+128M        -c9:cfg         \
+       -n10:0:+128M       -c10:var        \
+       -p /dev/mmcblk0
+   ```
+
+4. **Configure U-Boot to chainload Infix permanently** — reboot and
+   interrupt stock U-Boot again:
+
+   ```
+   setenv bootmenu_default 7
+   setenv bootcmd 'mmc read 0x46000000 0x4400 0x10000; go 0x46000000'
+   saveenv
+   reset
+   ```
+
+   The `bootcmd` reads the Infix U-Boot (at sector 0x4400/17408)
+   into RAM and jumps to it.  After `reset`, Infix boots from eMMC.
