Emcraft Systems 3.3. Known Problems & Limitations This section lists known problems and limitations of this release: 1. USB is not supported by this release on the M2S050-FG484 SOM since the USB ULPI interface is not supported on the M2S050-FG484 ES and PP (pre-production) devices. 2. CONFIG_KERNEL_IN_ENVM requires disabling CONFIG_ARM_UNWIND and CONFIG_EARLY_PRINTK. ID: RT 74683. Workaround: When enabling CONFIG_KERNEL_IN_ENVM in the kernel, disable CONFIG_ARM_UNWIND and CONFIG_EARLY_PRINTK. 3.

Emcraft Systems 5. M2S-FG484 SOM Board Linux Software Set-up 5.1. U-Boot Environment When the M2S-FG484 SOM board is reset, the Linux bootstrap will proceed to boot the UBoot firmware from the on-chip eNVM . Unless interrupted, U-Boot proceeds to load the Linux bootable image from the SPI Flash into the LPDDR and passes control to the Linux kernel entry point in LPDDR.

Emcraft Systems 5.3. Network Configuration You will have to update the network configuration of your board to match settings of your local environment. Typically, all you have to allow loading images over network from a TFTP server is update the U-Boot environment variables ipaddr (the board IP address) and serverip (the IP address of the TFTP server). Here is how it is done. Update ipaddr and serverip: M2S-FG484-SOM> setenv ipaddr 192.168.0.2 M2S-FG484-SOM> setenv serverip 192.168.0.
