I'm using the docker image to build the CAmkES ARM VMM project using roughly the instructions here: https://docs.sel4.systems/VM/CAmkESARMVM.html (they are slightly out of date).

Mike, Can you do a readelf of your outputted image to make sure its not compiling as a binary? If it is, you’ll have to use the “go” command in u-boot instead.

Hi Mike, Could you run "file images/capdl-loader-image-arm-tk1"? If you see "images/capdl-loader-image-arm-tk1: MS-DOS executable", the image is an EFI image, so bootefi command should help. Also, the link, https://docs.sel4.systems/Hardware/jetsontk1.html, may be helpful. Regards, Yanyan On Fri, 2020-01-24 at 15:24 -0500, Mike Clark wrote:

Thanks. I checked the output of file and it does list it as MS-DOS executable. Now I tried # fatload mmc 1 ${loadaddr} capdl-loader-image-arm-tk1 # bootefi ${loadaddr} After that I get nothing. The system just sits there and I get no further output. Anything else I can try? Is there any way to change the type of image that is getting created? I never had any issues with bootelf before and my old elf images still work. Mike On Sat, Jan 25, 2020 at 10:03 AM Shen, Yanyan (Data61, Kensington NSW) < Yanyan.Shen@data61.csiro.au> wrote:

Mike, Do you happen to have the “ApplyData61ElfloaderSettings()” command in your project files? function(ApplyData61ElfLoaderSettings kernel_platform kernel_sel4_arch) set( binary_list "tx1;hikey;am335x;odroidc2;imx8mq-evk;rockpro64;imx8mm-evk;hifive" ) set(efi_list "tk1") set(uimage_list "tx2") That sets any compiled images for the tk1 to be efi. You can remove the “tk1” from the “efi_list” and running “ccmake .” should allow you to choose the output setting as an elf. I’ve seen some issues where efi images don’t boot properly, but not with u-boot, so I can’t be sure your exact problem.

That sets any compiled images for the tk1 to be efi. You can remove the “tk1” from the “efi_list” and running “ccmake .” should allow you to choose the output setting as an elf. I’ve seen some issues where efi images don’t boot properly, but not with u-boot, so I can’t be sure your exact problem.

I'm using the docker image to build the CAmkES ARM VMM project using roughly the instructions here: https://docs.sel4.systems/VM/CAmkESARMVM.html (they are slightly out of date).
I do:

Then I copy the resulting image from the images directory to an SD card and put that in my TK1.
When U-Boot starts I use the following commands to try to boot
fatload mmc 1 0x10000000 capdl-loader-image-arm-tk1
bootelf 0x10000000
To which I get an error: No elf image at address 0x10000000
I tried with an older version of U-Boot (that worked following this same procedure about a year ago). It is U-Boot SPL 2014.10- rc2-g3127911 (Jun 07 2016 - 21:00:01)
I also tried updating U-Boot to U-Boot SPL 2020.01-00442- gc00bd81ae0 (Jan 10 2020 - 11:10:18 -0500). Same error.

One update on this. I pulled the sel4test-manifest project and built that for the TK1. When it built the efi image, I wasn't able to get it to work on my TK1 device. When I made the changes to the settings and got it to build the elf file instead, the tests ran just fine. I did double check to make sure I had done this.

Hi all, One additional update. I noticed updates to the camkes-arm-vm-manifest project today, so I pulled those in and tried a few things. I still have EFI turned off in the build. When I do init-build, if I have -DTk1Insecure=TRUE set, then when I try to boot the resulting image, I noticed that the cpu resets almost immediately. On the other hand, if I remove that flag, then when I try to boot the resulting image, I get nothing on the screen at all after issuing the bootelf command. Not sure if that helps trigger any thoughts. I'm at a loss for how to get the latest versions to boot. Mike On Mon, Jan 27, 2020 at 11:27 AM Mike Clark <undefinedspace@gmail.com> wrote:

Chris,
Looks like I might have spoken too soon. When I use go instead of bootelf, the board actually resets. Here are the log messages:

Doing readelf on the image that is being built doesn't work either

My old images from a year ago still boot just fine with bootelf. Any thoughts?

Mike,
Can you do a readelf of your outputted image to make sure its not compiling as a binary? If it is, you’ll have to use the “go” command in u-boot instead.
Thanks,

CAUTION: This email originated from outside the organization. Do not click links or open attachments unless you recognize the sender and know the content is safe. I'm using the docker image to build the CAmkES ARM VMM project using roughly the instructions here: https://docs.sel4.systems/VM/CAmkESARMVM.html (they are slightly out of date).
I do:
../init-build.sh -DAARCH32=TRUE -DCAMKES_VM_APP=vm_minimal -DPLATFORM=tk1
ninja
Then I copy the resulting image from the images directory to an SD card and put that in my TK1.
When U-Boot starts I use the following commands to try to boot
fatload mmc 1 0x10000000 capdl-loader-image-arm-tk1
bootelf 0x10000000
To which I get an error: No elf image at address 0x10000000
I tried with an older version of U-Boot (that worked following this same procedure about a year ago). It is U-Boot SPL 2014.10- rc2-g3127911 (Jun 07 2016 - 21:00:01)
I also tried updating U-Boot to U-Boot SPL 2020.01-00442- gc00bd81ae0 (Jan 10 2020 - 11:10:18 -0500). Same error.
Any thoughts or suggestions on how I get this to boot?

Hi Mike, Here is a copy of an EFI binary for the camkes-arm-vm tk1 project that runs on our tk1 development board internally: https://cloudstor.aarnet.edu.au/plus/s/FHVMZi0ei1Q6IYA. A reason why ELF works for seL4test and not for camkes-arm-vm is potentially because the Elfloader doesn't get started in monitor mode and is unable to start the kernel in Hyp mode.

Thanks Kent for looking at this. I downloaded the image you sent and it gets stuck after I issue the bootefi command. I let it sit for a few minutes and it never goes anywhere (console output is pasted below) You mentioned that "A reason why ELF works for seL4test and not for camkes-arm-vm is potentially because the Elfloader doesn't get started in monitor mode and is unable to start the kernel in Hyp mode. " What I don't understand about that is that I have a couple of images that I built back in August 2018 that still work just fine on this device when I use bootelf to boot them. seL4 starts up and drops to the VM and I can log into the VM.

Hi Mike,
You mentioned that "A reason why ELF works for seL4test and not for camkes-arm-vm is potentially because the Elfloader doesn't get started in monitor mode and is unable to start the kernel in Hyp mode. " What I don't understand about that is that I have a couple of images that I built back in August 2018 that still work just fine on this device when I use bootelf to boot them. seL4 starts up and drops to the VM and I can log into the VM. Ok.
Tegra124 (Jetson TK1) # fatload mmc 1 ${loadaddr} capdl-loader-image-arm-tk1 What is loadaddr set to? Does it fail with loadaddr set to 0x81000000?
Tegra124 (Jetson TK1) # bootelf ${loadaddr} ## Starting application at 0x817f0000 ... When trying to load an ELF with bootelf, I'm not sure what different versions of U-Boot do with regards to giving you an error if it unpacks the ELF over the top of the ELF. How does elfloading work with a loadaddr of around 0x84000000?
Which Jetson-tk1 board are you using?
Hi Kent, Thanks for the suggestions. My loadaddr was set to 0x81000000. I tried using 0x84000000 and it booted just fine in secure mode. This is on the Nvidia TK1. If I build with -DTk1Insecure=TRUE, I do have some issues.

Hi Mike, I tried the insecure setting and saw the exact same issue as you. The issue is that the insecure setting would disable access to a region of RAM at 0x40000000 that should still be accessible. Re-enabling this device is a 1 line change which I'll put up a PR for soon (see the patch below). Once I've made this change the insecure version boots to login. project projects/vm/ diff --git a/components/VM/src/modules/plat/tk1/init.c b/components/VM/src/modules/plat/tk1/init.c index dce7809..4bae973 100644 --- a/components/VM/src/modules/plat/tk1/init.c +++ b/components/VM/src/modules/plat/tk1/init.c @@ -38,7 +38,6 @@ static const struct device *linux_pt_devices[] = { static const struct device *linux_ram_devices[] = { #ifndef CONFIG_TK1_INSECURE &dev_rtc_kbc_pmc, - &dev_data_memory, &dev_exception_vectors, &dev_system_registers, &dev_ictlr, @@ -46,6 +45,7 @@ static const struct device *linux_ram_devices[] = { &dev_fuse, &dev_gpios, #endif /* CONFIG_TK1_INSECURE */ + &dev_data_memory, }; extern reboot_hooks_list_t reboot_hooks_list;
