Wally supports the following boards
ArtyA7
vcu108
vcu118
1. ArtyA7
2. vcu108
3. vcu118 (Do not recommend.)
# Quick Start
## build FPGA
cd generator
make <board name>
`cd generator
make <board name>`
example
make vcu108
`make vcu108`
## Make flash card image
ls /dev/sd* or ls /dev/mmc* to see which flash card devices you have.
Insert the flash card into the reader and ls /dev/sd* or /dev/mmc* again. The new device is the one you want to use. Make sure you select the root device (i.e. /dev/sdb) not the partition (i.e. /dev/sdb1).
cd $WALLY/linux/sd-card
`cd $WALLY/linux/sd-card`
This following script requires root.
./flash-sd.sh -b <path to buildroot> -d <path to compiled device tree file> <flash card device>
`./flash-sd.sh -b <path to buildroot> -d <path to compiled device tree file> <flash card device>`
example with vcu108, buildroot installed to /opt/riscv/buildroot, and the flash card is device /dev/sdc
./flash-sd.sh -b /opt/riscv/buildroot -d /opt/riscv/buildroot/output/images/wally-vcu108.dtb /dev/sdc
`./flash-sd.sh -b /opt/riscv/buildroot -d /opt/riscv/buildroot/output/images/wally-vcu108.dtb /dev/sdc`
Wait until the the script completes then remove the car.

Swap out the USB1 for USB0 or USB1 as needed.
