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-TF provides a test secure payload and they utilize the secure timer so I want to try this payload to confirm my board's timer works well.
In this case, I'm wondering can I still use the workspace I got to build the TSP for Juno board?
If I can, could you please give me some hints about how to modify the build scripts? If I can't, is there any other instructions about applying the TSP on Juno?
Thank you in advance.
Simon
Hi Ash Wilding,
I just met a problem about this issue again, could you please take a look?
Today I used the script from this link to get the latest OE-LAMP workspace and I want to use TSP with it. I used the script with the following configuration:
[64-bit] Juno Build from source Linux/Android lsk-4.4-armlt -- Supports Android OpenEmbedded LAMP -- 17.01
The workspace can be builtt. Both OE-LAMP and OPTEE secure payload are running on my Juno board normally.
However, when I tried to use TSP instead of OPTEE as you mentioned above ( I also patched 2 UART patches you shared), the booting will be stuck after these outputs:
Peripheral ID6:0x00000005 Peripheral ID7:0x000000B1 Programming NOR Flash PCIE clock configured... Testing motherboard interfaces (FPGA build 118)... SRAM 32MB test: PASSED LAN9118 test: PASSED KMI1/2 test: PASSED MMC test: PASSED PB/LEDs test: PASSED FPGA UART test: PASSED PCIe init test: PASSED PCIe MAC addresss 0002-F700-62E8 MAC addrs test: PASSED SMC MAC address 0002-F700-62E7 Setting HDMI0 mode for SVGA. Setting HDMI1 mode for SVGA. SoC SMB clock enabled. Testing SMB clock... SMB clock running Releasing system resets... UART0 set to SoC UART0 UART1 set to SoC UART1
I guess it's still something configured wrong with TSP or TSPD while I don't figure it out yet. If you know what's the problem or which part should I check for, please let me know.
Thank you!
Hi Simon,
Please can you try building ATF -without- the UART changes, and instead take the cover off your Juno and connect to FPGA UART0 (the J55 header), and see whether that works?
I'll try as soon as I get the office. However, I'm still wondering why for the OPTEE case the booting can run normally while the TSP cannot?
Hi Simon, I'm away from the office myself without physical access to a Juno board for the next ~week, so am limited in how much I can investigate this. I'll take a look when I can, though.
Hi Ash, would you get a chance to look into the case this week? I tried to open my Juno box while I don't find the FPGA UART port so I think it's better for me to just configure the TSP with SoC UARTs, thank you.
I think it would be wise to take this to a private case: please can you send an email to juno-support@arm.com and I'll pick it up.
Please do keep in mind, though, that this is starting to fall out of scope of what we officially support and so I may be limited in how much I can help you.
The problem you are experiencing is due to the recent changes to the way the deliverables communicate with the SCP - via SCMI rather than SCPI (see the Release Notes).
To fix this you need to build Trusted Firmware with the `CSS_USE_SCMI_SDS_DRIVER=1' flag set, i.e.:
CROSS_COMPILE=../gcc/bin/aarch64-linux-gnu- \ make PLAT=juno DEBUG=1 LOG_LEVEL=40 \ BL33=../out/SOFTWARE/bl33-uboot.bin \ SCP_BL2=../out/SOFTWARE/scp_bl2.bin \ CSS_USE_SCMI_SDS_DRIVER=1 \ SPD=tspd \ all fip
This will let you successfully boot when using the Linaro Release 17.07 board files.
To see the TSP output, attach an RS232 10-pin to DB9 connector to the J55 header on your Juno:
The UART uses the same 115200 8N1 setup as the main UARTs on the back of the board. You should see messages like this printed there:

Hope that helps,Ash.
Thank you very much, Ash! I think I can get the correct output now. I'm sorry that I don't see the last message about sending email to the support team. Have a good day.
No problem at all, glad to be of help :)
