The screenshot provides details about two partitions created in the SD card image. The first partition spans from sector 2,048 to sector 526,335, with a size of 256 MB and a W95 FAT file system. The second partition extends from sector 526,336 to sector 1,627,959, with a size of 537.9 MB and a Linux (ext4) file system.

Card
Upon completion of the build process, the resulting image files are stored in the out/boot2linux_SDcard/ directory. Refer to the list below:
...
ISPBOOOT.BIN: Binary file storing X-Boot, the first-stage boot-loader responsible for DDR SDRAM initialization and training, loading images of TF-A, OP-TEE, U-Boot, and initiating the execution of TF-A.
fip.img: Image file comprising images of Trusted Firmware-A (TF-A) and Open Portable Trusted Execution Environment (OP-TEE).
u-boot.img: Image file of the U-Boot boot-loader, the second-stage boot-loader responsible for loading and running the Linux kernel image.
uEnv.txt: Environment file for U-Boot. U-Boot imports environment variables from this file after initialization. If the uenvcmd command is defined in uEnv.txt, U-Boot executes the specified command after importing uEnv.txt.
uImage: Image file of the compressed Linux kernel with the U-Boot header.
ISP_SD_BOOOT.img: Image file for burning an SD card, containing all files in both partitions.

Platform
After creating your SD card, insert it into the SD card socket on your SP7350 platform.
Set the boot-switch to "Boot from SD card".
Connect the cable of your UART console.
Power on your SP7350 platform.
The platform will initiate booting from the SD card.
Once booted, you can enter your commands in the console.
For boot-switch selection guidance, please consult:
For example, if you are using SP7350 Evaluation Board, please set boot-selection switch SW2 to all OFF (1111) and SW3 to OFF-OFF-ON-ON (1100) for booting from SD card.
