Additional Linux microPlatform Targets

This section provides information on running the Linux microPlatform for other targets. It is provided on a best-effort basis.

Prebuilt Binaries

Several boards have reference builds provided by Foundries.io in the latest Linux microPlatform release, available at https://github.com/foundriesio/lmp-manifest/releases/latest.

Please note that these builds are provided for reference in hopes they are useful; not all receive equal testing.

Intel Core i7 (e.g. MinnowBoard Turbot)

Click to show/hide

Set MACHINE to intel-corei7-64 when setting up your work environment with the setup-environment script:

MACHINE=intel-corei7-64 source setup-environment [BUILDDIR]

At the end of the build, your build artifacts will be found under deploy/images/intel-corei7-64. The artifact you will use to flash your microSD card is lmp-gateway-image-intel-corei7-64.wic.gz.

Toradex Colibri iMX7D eMMC (Aster)

Click to show/hide

Set MACHINE to colibri-imx7 when setting up your work environment with the setup-environment script:

MACHINE=colibri-imx7 source setup-environment [BUILDDIR]

At the end of the build, your build artifacts will be found under deploy/images/colibri-imx7. The artifact you will use to flash your microSD card is lmp-gateway-image-colibri-imx7.wic.gz.

To flash your microSD card, run:

gunzip -f lmp-gateway-image-colibri-imx7.wic.gz
sudo dd if=lmp-gateway-image-colibri-imx7.wic of=/dev/mmcblkX bs=4M

Where /dev/mmcblkX is your SD card device.

To update U-Boot on Toradex Colibri iMX7D 1GB eMMC:

1. From the U-Boot prompt, update the device tree name and boot into LMP:

   Colibri iMX7 # setenv boot_targets "mmc1 mmc0 usb0 dhcp"
   Colibri iMX7 # setenv fdt_board aster
   Colibri iMX7 # run bootcmd
   

2. Once booted into LMP, flash U-Boot (as root):

   mkdir /tmp/boot
   mount /dev/mmcblk0p1 /tmp/boot
   echo 0 > /sys/block/mmcblk1boot0/force_ro
   dd if=/tmp/boot/u-boot-emmc.imx of=/dev/mmcblk1boot0 bs=512 seek=2
   

3. Reboot and from the U-Boot prompt update the device tree based on your module (e.g. Aster):

   Colibri iMX7 # setenv boot_targets "mmc1 mmc0 usb0 dhcp"
   Colibri iMX7 # setenv fdt_board aster
   Colibri iMX7 # saveenv
   Colibri iMX7 # reset
   

4. Boot LMP and change eMMC back to read-only (as root):

   echo 1 > /sys/block/mmcblk1boot0/force_ro

i.MX 8M Mini LPD4 Evaluation Kit

Click to show/hide

Build the manufacturing tools (mfgtools) by setting MACHINE to imx8mmevk and DISTRO to lmp-mfgtool when setting up your work environment with the setup-environment script:

DISTRO=lmp-mfgtool MACHINE=imx8mmevk source setup-environment [BUILDDIR]
bitbake mfgtool-files

At the end of the build, your manufacturing build artifacts will be found under deploy/images/imx8mmevk. The artifact you will use for flashing your eMMC device is mfgtool-files.tar.gz.

Build the Linux microPlatform image by setting MACHINE to imx8mmevk and DISTRO to lmp when setting up your work environment with the setup-environment script:

DISTRO=lmp MACHINE=imx8mmevk source setup-environment [BUILDDIR]
bitbake lmp-gateway-image

At the end of the build, your build artifacts will be found under deploy/images/imx8mmevk. The artifact you will use to flash your eMMC device is lmp-gateway-image-imx8mmevk.wic.

To flash your board, change the boot switch to download mode, connect a USB-C cable, turn on the board and run:

tar -zxvf mfgtool-files.tar.gz
cd mfgtool-files
sed -i 's/lmp-image-imx8mmevk.wic/lmp-gateway-image-imx8mmevk.wic/g' full_image.uuu
sudo ./uuu full_image.uuu

Power off the board, change the boot switch back to eMMC / SDHC3 and power it on again.

Note

Notice that the i.MX 8M Mini LPD4-EVK is different to i.MX 8M Mini D4-EVK. Find more information at NXP i.MX8 Mini.

SiFive HiFive Unleashed Freedom U540

Click to show/hide

Set MACHINE to freedom-u540 when setting up your work environment with the setup-environment script:

MACHINE=freedom-u540 source setup-environment [BUILDDIR]

Build the Linux microPlatform minimal image lmp-mini-image instead of the usual lmp-gateway-image, as there is no golang and docker support for RISC-V yet. At the end of the build, your build artifacts will be found under deploy/images/freedom-u540. The artifact you will use to flash your microSD card is lmp-mini-image-freedom-u540.wic.gz.

To flash your microSD card, run:

gunzip -f lmp-mini-image-freedom-u540.wic.gz
sudo dd if=lmp-mini-image-freedom-u540.wic of=/dev/mmcblkX bs=4M

Where /dev/mmcblkX is your SD card device.

Generic RISC-V 64 Machine

Click to show/hide

Set MACHINE to qemuriscv64 when setting up your work environment with the setup-environment script:

MACHINE=qemuriscv64 source setup-environment [BUILDDIR]

Build the Linux microPlatform minimal image lmp-mini-image instead of the usual lmp-gateway-image, as there is no golang and docker support for RISC-V yet:

bitbake lmp-mini-image

The artifacts required by QEMU are bbl (Berkeley Boot Loader + Kernel + initrd) and lmp-mini-image-qemuriscv64.ota-ext4 in deploy/images/qemuriscv64.

Boot the generic RISC-V target with QEMU

At the end of the build, change directory to where the build artifacts are found, then copy the image to where runqemu expects it and run it:

cd deploy/images/qemuriscv64
cp lmp-mini-image-qemuriscv64.ota-ext4 lmp-mini-image-qemuriscv64.ext4
runqemu nographic slirp qemuparams="-m 512"

SSH into guest

You can SSH into the RISC-V 64 guest by using the port forwarded to the RISC-V 64 guest:

ssh -p 2222 fio@localhost
