Hi, so I am now trying to load u-boot-spl.bin using teraterm as per process given in following link "http://processors.wiki.ti.com/index.php/AM335x_U-Boot_User%27s_Guide#UART" *1)I kept uart mode and throug teraterm transfered u-boot-spl.bin.*2)As per document "After image is successfully downloaded, the ROM code will boot it" I did not get display of character on teraterm.
3)Then I transfered u-boot.img and this time also did not get display of any character on teraterm.
Am I doing anything wrong while transfering files or is there any specific way to do this ?? What ouput I should get after loading both files ?? I am trying to load these files on am3517 crane board.
Boot Over UART
*Note*
- The release package does not contain the binary for UART boot. Please follow the steps mentioned herehttp://processors.wiki.ti.com/index.php/AM335x_U-Boot_User%27s_Guide#Building_U-Bootfor compiling u-boot and use the *spl/u-boot-spl.bin* file that is produced.
1. Switch ON EVM with switch settings for UART boothttp://processors.wiki.ti.com/index.php/AM335x_U-Boot_User%27s_Guide#UART. When “CCCC” characters appear on TeraTerm window, from the File Menu select Transfer --> XMODEM --> Send (1K mode) 2. Select “u-boot-spl.bin” for the transfer 3. After image is successfully downloaded, the ROM code will boot it. 4. When “CCCC” characters appear on TeraTerm window, from the File Menu select Transfer --> YMODEM --> Send (1K mode) 5. Select “u-boot.img” for the transfer 6. After image is successfully downloaded, U-Boot will boot it. 7. Hit enter and get to u-boot prompt “U-Boot# ”
