3.2 Software Requirements

The TI SoM eMMC is pre-flashed with the custom WIC image linked in the Software Files section. This image is based on an embedded Linux Yocto build with TPS65219 drivers backported from the mainline Linux and U-Boot repositories and includes an i.MX93 EVK dts file supporting the TI TPS65219 PMIC with the NXP I.MX 93 processor. The WIC image component versions are listed in Table 3-1.

Table 3-1 SDK Build Information
SDK Component Release Specific Build Information Version
Yocto 4.2.3 (Mickledore)
Linux kernel 6.1
UBoot 2023_24

Since the board is pre-flashed with the WIC image, no changes are needed by the user to use the TI SoM with the i.MX93 EVK. To boot from eMMC when the mother board is powered on, verify the boot mode switches are set to the 0000 default position
