TI814x 移植uboot时遇到的问题。

根据官方的指导手册《TI81XX PSP UBOOT User Guide》或《DM814x AM387x PSP U-Boot》操作

Boot Over UART

Note

The release package does not contain the binary for UART boot. Please follow the steps mentioned [] for compiling u-boot.min.uart

Switch ON EVM with . When “CCCC” characters appear on TeraTerm window, from the File Menu select Transfer --> XMODEM --> Send (1K mode)

Select “u-boot.min.uart” for the transfer

Press "Reset button" to initiate image download

After image is successfully downloaded, the ROM code will boot it.

Hit enter and get to u-boot prompt “TI-MIN#”

TI_MIN# Loading 2nd stage over UART  
 
  From the U-Boot-MIN prompt 
 TI_MIN# loadb 0x81000000  
 
  From TeraTerm Menu click “File -> Transfer -> Kermit -> Send”. 
  Select the 2nd stage u-boot image “u-boot.bin” built earlier and click “OPEN” button 
  Wait for download to complete 
 TI_MIN# go 0x81000000  
 
  You should get 2nd Stage u-boot prompt 
 TI8148_EVM#问题在上面那句 go 0x81000000 之后出现，Starting application at 0x81000000 ... 或者是还是回到第一阶段，问题的原因是我用的u-boot.bin是在编译u-boot.min.uart时得到的而实际上是要用编译u-boot.min.nand 或 u-boot.min.spi时得到的u-boot.bin，文档没读仔细 上文中提到用的是 Select the 2nd stage u-boot image “u-boot.bin”。
