How to format SD card for SD boot

https://xilinx-wiki.atlassian.net/wiki/x/EYMfAQ

1. Copy For the boot images, simply copy the files to the FAT partition. This typically will include BOOT.BIN, image.ub, and boot.scr

sudo mkdir -p boot
sudo mount /dev/sdd1 boot
sudo cp <PATH_TO_BUILD_DIR>/petalinux/<TARGET_NAME>/images/linux/system.bit boot/.
sudo cp <PATH_TO_BUILD_DIR>/petalinux/<TARGET_NAME>/images/linux/BOOT.BIN   boot/.
sudo cp <PATH_TO_BUILD_DIR>/petalinux/<TARGET_NAME>/images/linux/image.ub   boot/.
sudo cp <PATH_TO_BUILD_DIR>/petalinux/<TARGET_NAME>/images/linux/boot.scr   boot/.
sudo umount boot
sudo rm -rf boot

2. For the root file system, the process will depend on the format of your root file system image.

roofts.ext4 - This is an uncompressed ext4 file system image. To copy the contents to the root partition, you can use the following command:

sudo dd if=<PATH_TO_BUILD_DIR>/petalinux/<TARGET_NAME>/images/linux/rootfs.ext4 of=/dev/<DEV_NAME>

Change the Boot Mode of the Xilinx Zynq UltraScale+ MPSoC from XSCT

https://www.zachpfeffer.com/single-post/change-the-boot-mode-of-the-xilinx-zynq-ultrascale-mpsoc-from-xsct

following sequence changes to JTAG boot mode

xsct
connect
targets -set -nocase -filter {name =~ "*PSU*"}
stop
mwr  0xff5e0200 0x0100
rst -system
disconnect

following sequence changes to Quad-SPI (32b) mode

xsct
connect
targets -set -nocase -filter {name =~ "*PSU*"}
stop
mwr  0xff5e0200 0x2100
rst -system
con
disconnect

following sequence changes to SD0 (2.0) mode

xsct
connect
targets -set -nocase -filter {name =~ "*PSU*"}
stop
mwr  0xff5e0200 0x3100
rst -system
con
disconnect

following sequence changes to NAND mode

xsct
connect
targets -set -nocase -filter {name =~ "*PSU*"}

Load the bitstream and kernel via JTAG

# Go to petalinux project directory
cd <MY_PROJECT>

# Execute the command
petalinux-boot --jtag --kernel --fpga

Note: Make sure you power cycle the board before JTAG boot

How to create a .BSP file (Board Support File)

# Go to petalinux project directory
cd <MY_PROJECT>

# Execute the command
petalinux-package --bsp -p SpaceRfSocXilinxZcu208DevBoard -o SpaceRfSocXilinxZcu208DevBoard.bsp

Note: Make sure you power cycle the board before JTAG boot

How to Program the QSPI flash

# Go to petalinux project directory
cd <MY_PROJECT>

# Define default parameters
default_parameter="\
-flash_type qspi-x8-dual_parallel \
-blank_check -verify \
-fsbl images/linux/zynqmp_fsbl.elf"

# Execute the commands
program_flash -f images/linux/BOOT.BIN -offset 0x0000000 $default_parameter
program_flash -f images/linux/boot.scr -offset 0x3E80000 $default_parameter
program_flash -f images/linux/image.ub -offset 0x4000000 $default_parameter

Note: Assuming "qspi-x8-dual_parallel" for QSPI configuration

How to Program the NAND flash

# Go to petalinux project directory
cd <MY_PROJECT>

# Define default parameters
default_parameter="\
-flash_type nand-x8-single \
-blank_check -verify \
-fsbl images/linux/zynqmp_fsbl.elf"

# Execute the commands
program_flash -f images/linux/BOOT.BIN -offset 0x0000000 $default_parameter
program_flash -f images/linux/boot.scr -offset 0x3E80000 $default_parameter
program_flash -f images/linux/image.ub -offset 0x4180000 $default_parameter

How to force PS_ERROR_OUT for testing only

This procedure will force EM_ERR_ID_CSU_ROM=0x1, which will trigger PS_ERROR_OUT.

EM_ERR_ID_CSU_ROM is BIT0 of pmuErrorToPl[46:0] bus (A.K.A. "JTAG Error Register").

Refer to "JTAG Error Register" on pg 138 of Zynq UltraScale+ Device TRM UG1085 (v2.2).

xsct
connect
targets -set -nocase -filter {name =~ "*PSU*"}
 mwr -force 0x00FFD80528 0x8000FFFF
disconnect

How to dump all the PS diagnostic registers

cd submodule/axi-soc-ultra-plus-core
xsct
