Hi, I'm trying to cross-compile a program to run on arm versatile juno r2 development platform.
The system where I'm compilling is:
Linux lfpm1993-virtual-machine 4.13.0-43-generic #48~16.04.1-Ubuntu SMP Thu May 17 12:56:46 UTC 2018 x86_64 x86_64…
Hi,
I'm using Juno r0 and want to run Linux on that.
But there is something wrong when I power up Juno.

I've found an error in the wiki, specifically in TFTP (remote/network kernel) using U-Boot. I joined the community, thinking I could fix the problem, but still can't find any info on how to edit a specific page. Do I have to wait a certain amount of…
I am booting the juno board with coresight enabled in config file and the nodes in DT file are also correctly kept then also the coresight components are not getting registered though the board is booting
I use armplat_1810.py to set up juno board with Openembedded. After i delete the file system img and build it again, the file system img is not generated. Any clue why?
Hi, I have built an arm64 kernel image as per the step provided at https://community.arm.com/dev-platforms/w/docs/265/boot-an-arm64-kernel-on-the-juno-r1-platform .
After copying the image to /SOFTWARE, I am able to boot into the image. However, upon booting…
Hello all i'm trying to boot android on my juno board. i followed the procedure described here http://releases.linaro.org/latest/android/armv8-android-juno-lsk and also here Setting up Android on Juno

Hi experts,
Recently, I'm trying to evaluate the code execution time when using the A53 core and the A57 core.
However, my result shows A53 core is much faster than the A57 core, which does not make sense to me so I want to share my case here to see…
Hello
I want to ask if the ARM Juno board has support to run Android 7 or 8 along side OPTEE.
Thanks
Hi experts Ash Wilding, Mark Nicholson,
I'm trying to configure some peripherals like NIC of the Juno as the secure peripherals.
By checking the material I found that TrustZone Protection Controller(TZPC) can achieve this goal while I do not find any…
Hi,
I am using the DSTREAM and DS-5 to trace the execution on my Juno r1 board. It worked well before. However, i suddenly met an issue that i cannot use the 4G trace buffer inside the DSTREAM. If i choose the DSTREAM trace buffer, clicking the "start…
Hi,
I upgraded my Juno r1 board with the most recent Linaro release (18.01). Everything works well except the network. I tried both the android build and openembedded build, however, both builds failed to connect to the network. Once i revert it back to…
Hi,
Recently, i tried to update the firmware in my Juno r1 board. Specifically, i was trying to use the linaro release script workspace_1801.py with Openembedded LAMP. However, after i copied the content in the "<workspace>/recovery" fold to the MMC card…
Hi experts,
I'm using a Juno r1 board which is deployed with a Yukon Ultra-2 Ethernet Controller. Now I'm working on a project which is trying to protect some registers of this NIC based on the TrustZone technology so the best solution for me is configuring…
Hi all,
I am trying to use one Cortex-A57 (debugger) core to debug a Cortex-A53 core (target) on Juno board. According to the armv8 architecture manual, i may halt the the target and use EDITR instruction to force the target execute instructions. So,…
Hi all,
I found that the SPNIDEN and SPIDEN signal on the Juno board can be driven by the internal driver (SSC_DBGCFG_STAT register) or the debug authentication register in SCC. However, i cannot find the debug authentication register in SCC described…
Hi, experts Ash Wilding Mark Nicholson,
I'm wondering for the multicore ARM architecture, are all CPU cores sharing one set of general purpose registers (X0 - X30) or each CPU core has its separate registers? My feeling is that each core has its own…
Hi experts Ash WildingMark Nicholson Michele Wilkinson,
I configured my Juno board as this instruction and my workspace is initialized by the script from that page too.
Now I met some unknown issues when setting secure timer for my board. I find the ARM…
Hi there,
After setting up the board followed by the instruction, I connect both UART ports with my computer. For my board one port shows normal world output while other one shows OP-TEE output.
In this case, I'm wondering is there anyway for me to print…
Hi experts Ash Wilding Mark Nicholson,
I have a Juno r1 board and I'm using it as the instruction of this page's "Building from source" section.
Now I want to update some secure related registers (e.g., SCR_EL3) for my board. These…
Hi experts,
I'm using the Juno r1 board with Linaro OPTEE released normal OS + secure OS.
After some tests, I find that every time when the Client Application (CA) calls the function of a Trusted Application (TA), the secure OS is just running on…
Hi,
I am trying to use arm trusted firmware with my own BL32 (with 0xFF000000 entry point as specified). I want BL31 switch to my secure world that generate smc (aftersome init) to switch to normal world.
For that I use this compilation configuration:
Hi experts,
I'm using a Juno r1 board for some cache-related research experiment so I'm studying the related memory attributes such as cacheability and shareability.
I found the manual mentioned that: " the division between inner and outer is…
Hey guys,
I need your help because I have to count the number of L2 instruction access, miss and hits. But in the data-sheet I did not find the events that I have to count.
I found it in the ARM V8 data-sheet. Therefore, is it usable on A72 & A53 even…
