3.2 U-Boot Console Output

Here we need set up minicom to open target board serial console.

• sudo minicom -s

• choose “Serial port setup”

  • set “Serial Device” to /dev/ttyUSB0

  • set “Bps/Par/Bits” to 57600 8N1

  • set “Hardware Flow Control” to No.

• choose "Save setup as dfl"

• choose "Exit"

After setting up like above, it can open one terminal on Ubuntu. Next time you can run directly:

sudo minicom

This command would open the console for your U-Boot.

Note: if you are working from virtual machine and want to use the serial console from it, you will also need to pass-through related serial device to your VM.

3.3 Loading U-Boot With GDB

Open another terminal on Ubuntu and run the following commands:

cd /opt/analog/cces-linux-add-in/1.1.0/uboot-sc58x-1.1.0/bin

$ arm-none-eabi-gdb u-boot-sc58x-ezkit-hpc

(gdb) target remote :3333

Remote debugging using :3333 0x200bfff0 in ?? ()

(gdb)

load init stub to do early cpu and ddr init

(gdb) load init-sc58x-ezkit-hpc.elf

(gdb) c

load u-boot and run

Ctrl + C

(gdb) load u-boot-sc58x-ezkit-hpc

(gdb) c

U-Boot should now be running in RAM on your target board, from the minicom opened earlier you should be able to get the U-Boot console output.

3.4 Flash U-Boot to SPI Flash

On your host computer :

1) cp u-boot-sc58x-ezkit-hpc.ldr /tftpboot/u-boot.ldr

Ensure your board is connected to the same LAN network as your host machine, run the following command to set up the U-Boot environment in the minicom console

2) dhcp

3) set serverip $your_host_ip

4) run update

5) save
