Patching PMU 2018.3

[rrx]

Can get patch/debug to work with my pmu build ...I followed all listed here:

https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18842475/PetaLinux+Yocto+Tips#PetaLinuxYoctoTips-HowtopatchPMUFirmwareinPetaLinuxProject

with the following bb recipe I should at least see debug ... but nothing ... Any ideas ???? ... this is in recipes-bsp/pmu-firmware:

[pmu-firmware]$ ls
files pmu-firmware_%.bbappend
[pmu-firmware]$ cat pmu-firmware_%.bbappend
SRC_URI_append = " \
file://0001-pmu.patch \
"

FILESEXTRAPATHS_prepend := "${THISDIR}/files:"

# Enable appropriate PMUFW debug flags
YAML_COMPILER_FLAGS_append = " -DDEBUG_MODE -DXPFW_DEBUG_DETAILED"
[rrzepiela@enge6kbldprd01 pmu-firmware]$ ls files/
0001-pmu.patch
[pmu-firmware]$ cat files/0001-pmu.patch

Hi @rrx ,

To patch and verify(optional) PMUFW below is the steps

1. Save PMUFW build artifacts by adding this variable in petalinuxbsp.conf 

   $ tail project-spec/meta-user/conf/petalinuxbsp.conf
   
   RM_WORK_EXCLUDE += "pmu-firmware"

2. Clean the sstate and rebuild pmu-firmware recipe 

   $ petalinux-build -c pmu-firmware -x cleansstate
   $ petalinux-build -c pmu-firmware

3. Now in ${TMPDIR}/work/plnx_zynqmp-xilinx-linux/pmu-firmware directory search for yoru patch content.

To add BSP flags(debug mode) in PMUFW: For example if you want to enable https://github.com/Xilinx/embeddedsw/blob/release-2018.3/lib/sw_apps/zynqmp_pmufw/misc/xfpga_config.h#L34 debug is Xil BSP libraries

#Add BSP flags for PMUFW
YAML_BSP_CONFIG += "debug_mode"
YAML_BSP_CONFIG[debug_mode] = "set,true"
