From c60d660b6dcd398136df80e6b26f31fc3a4cc8e3 Mon Sep 17 00:00:00 2001 From: Oleksandr Suvorov Date: Wed, 2 Jun 2021 12:07:07 +0300 Subject: udev: colibri-imx7: sync emmc and nand udev rules TEZI uses the same machine colibri-imx7 for both eMMC and NAND variants of the module. For correct work with Colibri iMX7 eMMC TEZI requires symlinks emmc* generated by toradex udev rules - it allows TEZI to unblock boot-partitions for writing operations on start. The udev "emmc*" rules are triggered by the block instances of the device usdhc@30b60000. The usdhc@30b60000 device disabled by default in the device tree for Colibri-iMX7 NAND SoM, so that the "emmc*" doesn't affect the NAND module. Adding "emmc*" rules to the 99-toradex.rules for colibri-imx7 machine fixes several TEZI issues for Colibri iMX7 eMMC, i.e. this one: Processing blockdev: "mmcblk0boot0" Running Command: "/usr/sbin/blkdiscard" ("/dev/mmcblk0boot0") Progress: "Toradex Embedded Linux Reference Minimal Image (UPSTREAM): Erasing partition" Output: "blkdiscard: /dev/mmcblk0boot0: BLKDISCARD ioctl failed: Operation not permitted\n" Finished with exit code: 1 Related-to: TEI-851 Signed-off-by: Oleksandr Suvorov --- recipes-core/udev/files/colibri-imx7/99-toradex.rules | 3 +++ 1 file changed, 3 insertions(+) diff --git a/recipes-core/udev/files/colibri-imx7/99-toradex.rules b/recipes-core/udev/files/colibri-imx7/99-toradex.rules index 56f454f..ae80f8b 100644 --- a/recipes-core/udev/files/colibri-imx7/99-toradex.rules +++ b/recipes-core/udev/files/colibri-imx7/99-toradex.rules @@ -5,6 +5,9 @@ ACTION=="add", ATTRS{iomem_base}=="0x30890000", SYMLINK+="colibri-uartb" ACTION=="add", ATTRS{iomem_base}=="0x30880000", SYMLINK+="colibri-uartc" ACTION=="add", KERNEL=="watchdog", DRIVERS=="rn5t618-wdt", SYMLINK+="colibri-watchdog" ACTION=="add", SUBSYSTEM=="spidev", KERNELS=="30840000.*spi", SYMLINK+="colibri-spi-cs%n" +KERNEL=="mmcblk[0-9]", ENV{DEVTYPE}=="disk", KERNELS=="30b60000.usdhc", SYMLINK+="emmc" +KERNEL=="mmcblk[0-9]boot[0-9]", ENV{DEVTYPE}=="disk", KERNELS=="30b60000.usdhc", SYMLINK+="emmc-boot%n" +KERNEL=="mmcblk[0-9]p[0-9]", ENV{DEVTYPE}=="partition", KERNELS=="30b60000.usdhc", SYMLINK+="emmc-part%n" SUBSYSTEM=="iio", KERNELS=="iio:device0", RUN+="/etc/udev/scripts/toradex-adc.sh" ACTION=="add|change", KERNEL=="mmcblk[0-9]", ENV{DEVTYPE}=="disk", KERNELS=="30b40000.usdhc", SYMLINK+="colibri-sd" ACTION=="add|change", KERNEL=="mmcblk[0-9]p[0-9]*", ENV{DEVTYPE}=="partition", KERNELS=="30b40000.usdhc", SYMLINK+="colibri-sd-part%n" -- cgit v1.2.3
