Hi all,
I got a board TDA2Ex-17 Vision EVM Kit (EVMX777G-01-40-00, this part number cannot be recognized). Then I tried three way of booting from SD card :
- Refer to the guide[1], I prepare the SD card with mksdboot.sh --> Boot ok
- Copy MLO and u-boot.img in ${TISDK}/prebuilt-images to ${SDCARD}/boot. The SD card is prepared with approach 1 --> Boot ok
- Execute below commands in terminal, copy compiled MLO and u-boot.img into ${SDCARD}/boot. The SD card is prepared with approach 1 --> Boot failed with no print in UART
export CROSS_COMPILE=arm-linux-gnueabihf- export PATH=/home/${USERNAME}/gcc-linaro-7.2.1-2017.11-x86_64_arm-linux-gnueabihf/bin:$PATH export SDKBASE=/home/${USERNAME}/tisdk/board-support export ARCH=arm export LDTS=/home/${USERNAME}/tisdk/board-support/linux/arch/arm/boot/dts export UDTS=/home/${USERNAME}/tisdk/board-support/u-boot/arch/arm/dts export UDBOOT=/media/${USERNAME}/rootfs/boot cd ${TISDK}/board-support/u-boot make dra7xx_evm_defconfig
Is there anything wrong ? I hope someone can share me some insight. Thanks a lot !
