## How to have fun with the GAPuino on Linux
In general, follow this README: https://github.com/GreenWaves-Technologies/gap_sdk/blob/master/README.md
PLUS
### Fix the -Werror flag to make openocd compile
Comment this line in gap_sdk/tools/gap8-openocd
`GCC_WARNINGS="${GCC_WARNINGS} -Werror"`
### Fix libmpfr version bug
`sudo ln -s /usr/lib/libmpfr.so.6 /usr/lib/libmpfr.so.4`
### Fix bug in load_jtag_hyper function
* Grep for `load_jtag_hyper` in the source directory of the SDK
* Make sure all function definitions have the signature `load_jtag_hyper(self)`
### Enable hyperflash boot
* This is supposed to be a one-time operation
* Run the following commands
`source ~/gap_sdk/configs/gapuino_v2.sh`
`openocd -f interface/ftdi/gapuino_ftdi.cfg -f target/gap8revb.tcl -f ./tcl/jtag_boot.tcl -f ./tcl/fuser.tcl`
* Open a second terminal and continue with
`source ~/gap_sdk/configs/gapuino_v2.sh`
`telnet localhost 4444`
* In the openocd terminal run (adapt path to directory if necessary)
`fuse_hyperflash_boot /home/$USER/gap_sdk/tools/gap8-openocd-tools`
* Unplug the gapuino, it SHOULD now boot from hyperflash
* Add `PLPBRIDGE_FLAGS += -f -hyper` to your Makefile
* I could only boot from flash, when I hit `make` and the `openocd` command after every flash
