Flashing
 | NOTE: During configuration or flashing a device, the only things that should be hooked to the device is the computer and power. |
Flashing OpenWrt
 | Devices with Broadcom WiFi chipsets have limited OpenWrt supportability (due to limited FLOSS driver availability for Broadcom chips). Consider this when choosing a device to buy, or when deciding to flash OpenWrt on your device because it is listed as supported. See Broadcom WiFi for details. |

imx: cortexa7: add support for TechNexion PICO-PI-IMX7D
TechNexion PICO-PI-IMX7D is a NXP i.MX 7Dual based development board in
the well-known "Raspberry Pi" form factor, comprising of PICO-IMX7 SoM
and the PICO-PI-IMX7D carrier board.
Usually bundled with a 5" 800x480 LVDS display with I2C touchscreen and
an Omnivision OV5645 camera on a MIPI CSI bus, on a daughterboard. The
board was previously used primarily with "Android Things" ecosystem, but
the project was killed by Google.
This would not be possible, if not for the great tutorial of setting up
Debian on this board, by Robert C. Nelson [1].
Hardware highlights:
CPU: NXP i.MX 7Dual SoC, dual-core Cortex-A7 at 1000 MHz
RAM: 512 MiB DDR3 SDRAM
Storage: 4 GB eMMC
Networking:
- built-in Gigabit Ethernet with Atheros AR8035 PHY,
- Broadcom BCM4339 1x1 802.11ac Wi-Fi (over SDIO) + Bluetooth 4.1
(over SDIO + UART + IS2) combo, with Hirose u.FL connector on the
board,
- dual CAN interfaces on the 40-pin connector,
Interfaces:
- USB-C power input plus USB 2.0 OTG host/device port,
- single USB-A host port,
- serial console over built-in FT232BL USB-UART converter with
micro-USB connector (configuration: 115200-8-N-1),
- analog audio interface with TRRS connector in CTIA standard,
- SPI, I2C and UART interfaces available on the 40-pin,
- mikroBUS connector,
- I2C connector for the optional touch panel,
- parallel LCD output for the optional display,
- MIPI CSI connector for the optional camera
Installation:
1. Connect the serial console to debug USB connector and the terminal of
choice in another window, at 115200-8-N-1. Ensure you can switch to
it quickly after next step.
2. Power-on the board from your PC. Ensure your PC can supply required
current, the board can take more than 1 A in the peak load during
booting and brownout will result in power-on reset loop. Preferably,
use charging-capable USB port or connect through self-powered USB
hub. If U-Boot is present already on the eMMC, interrupt the booting
sequence by pressing any key and skip to point 7.
3. Ensure the boot mode jumpers J1 and J2 are in correct position for
USB recovery:
2 6 2 6
--------------
|o o-o||o-o o|
|o o-o||o-o o|
J1 -------------- J2
1 5 1 5
The jumpers are located just underneath the 40-pin expansion header
and are of the smaller 2 mm pitch.
4. Download and build 'imx_usb_loader' from:
https://github.com/boundarydevices/imx_usb_loader.
5. Power-on the board again from your PC through USB OTG connector.
6. Use 'imx_usb_loader' to load 'SPL' and 'u-boot-dtb.img' to the board:
$ sudo imx_usb u-boot-pico-pi-imx7d/SPL
$ sudo imx_usb u-boot-pico-pi-imx7d/u-boot-dtb.img
7. Switch to the terminal from step 2 and interrupt boot sequence by
pressing any key within 2 seconds.
8. Configure mmc 0 to boot from the data partition and disable access to
boot partitions:
=> mmc partconf 0 0 7 0
This only needs to be set once. If you were running Debian previously,
this is probably already set.
9. Enable USB mass storage passthrough for eMMC from U-boot
=> ums 0 mmc 0
10. Optionally, backup previous eMMC contents by reading out its image.
11. Copy over the factory image to the USB device, for example:
$ sudo dd if=openwrt-imx-cortexa7-pico-pi-imx7d-squashfs.combined.bin \
of=/dev/disk/by-id/usb-Linux_UMS_disk_0-0:0 \
bs=8M status=progress oflag=direct
12. Detach USB MSC interface from your PC and U-Boot by pressing Ctrl+C.
13. Ensure that boot mode jumpers are at the default settings for eMMC
boot:
2 6 2 6
--------------
|o-o o||o o-o|
|o-o o||o-o o|
J1 -------------- J2
1 5 1 5
If they are not, power-off the board, restore them and power-on the
board again. Otherwise, if jumpers are set, just reset the board from
U-Boot CLI:
=> reset
14. The installation is now complete and board should boot successfully.
Upgrading: just use sysupgrade image, as usual in OpenWrt.
Known issues/current limitations:
- OV5645 camera - not described in upstream device tree as of kernel
5.15. There are staging drivers present in upstream Linux tree for
i.MX 7 CSI, MIPI-CSI and video mux, and the configuration is there in
imx7s.dtsi - so this is expected to get supported eventually,
- on-chip ADCs are disabled in upstream device tree, so the kernel
driver remains disabled as well.
