# FSBL
|
|
|
|
FSBL code is at https://github.com/Xilinx/embeddedsw/
|
|
|
|
there:
|
|
```sh
|
|
cd lib/sw_apps/zynq_fsbl/src/ && make BOARD=zed CFLAGS=-DFSBL_DEBUG_INFO
|
|
```
|
|
|
|
# Building
|
|
|
|
Requirements [TBC]:
|
|
- cmake
|
|
- arm-none-eabi-gcc
|
|
|
|
```sh
|
|
cmake -DFSFW_OSAL=freertos -DFSFW_ADD_HAL=OFF -DCMAKE_TOOLCHAIN_FILE=../bsp_z7/cmake/arm-none-eabi.toolchain ..
|
|
```

# Debugging on zedboard
|
|
|
|
Requirements [TBC]:
|
|
- OpenOCD
|
|
- arm-none-eabi-gdb
|
|
|
|
Connect to zedboard jtag and uart usb port.
|
|
|
|
On PC connected to zedboard jtag usb port:
|
|
```sh
|
|
openocd -f board/digilent_zedboard.cfg
|
|
```
|
|
|
|
To use JTAG Boot for the obsw, you first need to run the FSBL once.
|
|
|
|
On build PC (adapt IP if different from debugging PC):
|
|
```sh
|
|
arm-none-eabi-gdb fsbl.elf
|
|
>target extended-remote localhost:3333
|
|
>load
|
|
>cont
|
|
>^C^D^D
|
|
```
|
|
|
|
Then load the actual obsw:
|
|
```sh
|
|
arm-none-eabi-gdb fsbl.elf
|
|
>target extended-remote localhost:3333
|
|
>load
|
|
>cont
|
|
```
|
|
|
|
Uart usb port should output something at 115200baud, (I use moserial to monitor).
