Build env

Combining the red-pitaya-notes and the stock red pitaya FPGA bit file to create a suitable package to put on the red pitaya.

pretty much red-pitaya-notes (for the ubuntu os) + the FPGA from the stock os.

Communication

Trying using the uart. pavel - change the config in the scripts/bare_meal file to ps7_uart_1 [get_os] for both ... 
Did not work. Printf was still not in the libary when rebuilt.

moving the IPC further downwards may help?

Need to find out how the mem is allocated.

The uboot config patch is in RedPitaya/FPGA/release1/sw/uboot/uboot_patch.txt <- you don't need to manually use it to build the RP os
https://github.com/clade/RedPitaya/tree/master/python

or just use a proper distro:

xpseudo_asm_gcc.h - from the XAPP1078 - has memory barrier instructions in the header for 

SD card file discr.rst

boot.bin -> packed using bootgen, contains

• FSBL
• u-boot
• uImage
• uRamDisk.image.gz
• devicetree.dtb

devicetree.dts made by libgen -> what creates it? u-boot.elf -> compiled from u-boot, stock FSBL -> loads the rest - what configures this? not the devicetree

bootgen controled by b.bif in the RP root. bootgen -image b.bif -o i build/boot.bin

kernel build process

Config: OS/linux/config/rp_defconfig PROBABLY Has the remoteproc and xlnx-remoteproc modules as drivers, but 'modprobe remoteproc' complains of no dir /lib/modules/

Do the steps in red-pitaya-notes. That works.
