Thanks Alex, So in this JTAG example does the run command begin the 3 step boot process you outlined? Also how should I be generating sel4bench-image-arm-zynq7000? Right now I am working from the sel4test repository https://github.com/seL4/sel4test configured to target Zynq-7000. When I try the "dow images/sel4bench-image-arm-zynq7000" on images generated using the standard make command and also with make build-binary and make build-uBoot, I get an error: Code 16 Time 1485875053070 Format {Invalid context}. Looking at the configuration this seems to be designed for the Xilinx ZC706, ARMv7a, Cortex A9. However the zed board has a ZC702. Would this be the source of my problem or should sel4 work with the ZC702 as well?

So ${loadaddr} can be anything that you like, as long as it does not overwrite any part of u-boot or occupy the space at which the ELF sections will be copied. Loading from SD can be quite awkward during development. I recommend using JTAG via the XMD tool. Here is an example of the required XMD commands: ------------ connect arm hw rst fpga -f hardware/bitstream.bit source hardware/ps7_init.tcl ps7_init ps7_post_config dow images/sel4bench-image-arm-zynq7000 run exit ------------- - Alex On Mon, 2017-01-30 at 16:04 +0000, Brandon, Jeffrey - 0553 - MITLL wrote:
Hi,
I’ve been trying to get seL4 running on a Zedboard and I was wondering if there was any documentation on how to boot sle4 from an SD card.
I’ve read
http://sel4.systems/pipermail/devel/2016-December/001160.html
and
https://sel4.systems/Info/Hardware/General/
which mentions using ${loadaddr} but that doesn’t seem to be defined on the Zedboard’s u-boot.
So far I’ve compiled the image targeting the zynq7000 and used the mkimage command from the general hardware page to try u-boot’s fastboot, but fastboot doesn’t seem to be available on the zynq either.
I am a bit of a novice here. I worry that the solution may be simple but I am currently taking shots in the dark. I wanted to ask this list for any resources you may be aware of for getting sel4 test cases running on the Zed.
Thanks for the help,
Jeff Brandon
