| − | == Preliminary setup ==
| |
| − | * Make sure to power off the CM-T3530 evaluation platform
| |
| − | * Connect the host PC to the SB-T35 base-board (connector P12) via the serial cable supplied with the evaluation kit.
| |
| − | * Start terminal emulation software on your PC. Set baud rate to 115200 bps, 8 bit per frame, 1 stop bit, no parity, no flow control.
| |
| − | * Turn on the CM-T3530 evaluation system. The U-Boot boot-loader will start and you will get a command prompt.
| |
| − | {{Note|If the boot settings of your CM-T3530 are different than default, you may need to press and hold ^C while turning the CM-T3530 on, in order to get command prompt.}}
| |
| − | CM-T3530 firmware can be updated from an MMC/SD card or using network TFTP download.
| |
| − | Both methods are performed from the U-Boot command line.
| |
| − | | |
| − | CM-T3530 Firmware consists of two components: X-Loader and U-Boot. The U-Boot bootloader can be installed and updated independently without updating the existing X-Loader. Please continue to [[CM-T3530: U-Boot: Firmware Update#CM-T3530_U-Boot_Update|CM-T3530 U-Boot Update]] for U-Boot installation instructions.

| − | {{Warning|'''X-Loader can be installed only to completely erased NAND flash! The procedure below erases the entire NAND flash!'''}}
| |
| − | === MMC/SD card ===

| |
| − | * Insert the MMC/SD card into the SD socket (P13) on SB-T35.
| |
| − | * Start the U-Boot MMC subsystem and check that your storage device is ready and contains the X-Loader binary
