Well, another blog post on how to build a modified FSBL for ZYNQ. Using the patch which I demonstrated how to make in the previous post and a modified version of the fsbl_%.bbappend file which I received from the Xilinx Forum post regarding this I was able to make a working FSBL with my patch. The modified fsbl_%.bbappend file is shown below.<\/p>\n
# Force to use embeddedsw repository\r\nEXTERNALXSCTsrc=\"\"\r\nEXTERNALXSCTSRC_BUILD = \"\"\r\n\r\n#Enable FSBL debug flags\r\nYAML_COMPILER_FLAGS_append = \" -DFSBL_DEBUG\"\r\n\r\n# Patch FSBL\r\nSRC_URI_append += \"file:\/\/0001-fsbl.patch\"\r\nFILESEXTRAPATHS_prepend := \"${THISDIR}\/files:\"\r\n<\/pre>\nHere are the steps used to create the FSBL<\/p>\n
First run petalinux-create to build a petalinux project. Point it at the appropriate BSP.<\/p>\n
$ petalinux-create --type project --source \/tools\/xilinx\/bsp\/xilinx-zc706-v2017.4-final.bsp<\/pre>\nThen copy the fsbl_%.bbappend file into the project.<\/p>\n
$ cp fsbl_%.bbappend xilinx-zc706-2017.4\/project-spec\/meta-user\/recipes-bsp\/fsbl\r\n$ cp 0001-fsbl.patch xilinx-zc706-2017.4\/project-spec\/meta-user\/recipes-bsp\/fsbl\/files<\/pre>\nNext run a petalinux-build to make the bootloader<\/p>\n
$ petalinux-build --project xilinx-zc706-2017.4 -c bootloader<\/pre>\nWhen all is said and done you will get a zynq_fsbl file in xilinx-zc706-2017.4\/images\/linux\/zynq_fsbl.elf.<\/p>\n
This procedure works for 2017.4 and 2016.4.<\/p>\n
Building from the git checkout<\/h1>\n
Alternatively you can build from the git checkout where you made the patch. This seems much simpler but it doesn’t work for me with petalinux 2016.4.<\/p>\n
From the embeddesw checkout directory cd to lib\/sw_apps\/zynq_fsbl_src and run the following command.<\/p>\n
$ make BOARD=zc706<\/pre>\nThis should build the file fsbl.elf in the src directory.<\/p>\n
When I try to build this for 2016.4 I get a bunch of errors. They differ depending on how I set the CC variable on the make command line. If I don’t set it I get errors about arm-xilinx-eabi-gcc: Command not found. If I set CC=arm-none-eabi-gcc then I get this<\/p>\n
arm-none-eabi-gcc -c pcap.c -o pcap.o -I..\/misc\/\/ps7_cortexa9_0\/include -I.\r\nIn file included from pcap.c:96:0:\r\npcap.h:65:21: fatal error: xdevcfg.h: No such file or directory\r\ncompilation terminated.\r\nMakefile:97: recipe for target 'pcap.o' failed\r\n<\/pre>\nIf anyone knows what to do about this I’m all ears.<\/p>\n","protected":false},"excerpt":{"rendered":"
