Juno

The instructions here will tell how to run OP-TEE on the Juno board. The instructions has been tested and verified on the Juno r0 revision (see Juno revisions for more details).

Regular build

First step is to start out by following the instructions in the Get and build the solution as described in build.

Deploy files on the device

Enter the firmware console on the Juno board and press enter to stop the auto boot.

ARM V2M_Juno Firmware v1.3.9
Build Date: Nov 11 2015

Time :  12:50:45
Date :  29:03:2016

Press Enter to stop auto boot...

Enable FTP at the firmware prompt.

Cmd> ftp_on
Enabling ftp server...
 MAC address: xxxxxxxxxxxx

 IP address: 192.168.1.158

 Local host name = V2M-JUNO-A2

Flash the binary by running

Note

Use the IP address from output from previous command.

$ make JUNO_IP=192.168.1.158 flash

Once all binaries have been transferred, reboot the board:

Cmd> reboot

Update the flash layout

The flash layout for Juno may need to be updated for the flashing above to work. If flashing fails or if TF-A refuses to boot due to wrong version of the SCP binary, then the flash(-layout) needs to be updated. To update the flash please follow the instructions at Arm’s old release notes page selecting one of the zips under “Development boards / Juno / Prebuilt configurations” and flash it as described at Run the Arm Platforms deliverables on Juno.

GlobalPlatform testsuite support

Note

Depending on the Juno pre-built configuration, the built ramdisk.img size with GlobalPlatform testsuite may exceed its pre-defined Juno flash memory reserved location (image.txt file). In that case, you will need to extend the Juno flash block size reserved location for the ramdisk.img in the image.txt file accordingly and follow the instructions under “5.7.1 Update flash and its layout”.

Example

Example with juno-latest-busybox-uboot.zip. The current ramdisk.img size with GlobalPlatform testsuite is 8.6 MBytes and that is too big to fit in the default configuration, therefore we need to make adjustments to the flash layout. You will do that by making changes to /JUNO/SITE1/HBI0262B/images.txt. I.e., from:

NOR4UPDATE: AUTO                 ;Image Update:NONE/AUTO/FORCE
NOR4ADDRESS: 0x01800000          ;Image Flash Address
NOR4FILE: \SOFTWARE\ramdisk.img  ;Image File Name
NOR4NAME: ramdisk.img
NOR4LOAD: 00000000               ;Image Load Address
NOR4ENTRY: 00000000              ;Image Entry Point

to extending the Image Flash Address to 16MB

NOR4UPDATE: AUTO                 ;Image Update:NONE/AUTO/FORCE
NOR4ADDRESS: 0x01000000          ;Image Flash Address
NOR4FILE: \SOFTWARE\ramdisk.img  ;Image File Name
NOR4NAME: ramdisk.img
NOR4LOAD: 00000000               ;Image Load Address
NOR4ENTRY: 00000000              ;Image Entry Point

GCC > 5.x support

Note

In case you are using the latest version of the OP-TEE Arm Juno build (i.e., juno.xml manifest), then the ramdisk.img built with a GCC version newer than 5.x will be bigger than built with older GCC versions. This means that you will need to update the sections in image.txt that tells where various images will start (see the image.txt file).

To solve this problem you will need to extend the Juno flash block size reserved location for the ramdisk.img and decrease the size for other images in the image.txt file accordingly in the same manner as described in the previous section above.

For example with juno-latest-busybox-uboot.zip. The current ramdisk.img size with GCC 5.x compiler is 29.15MB and therefore we will need to extend that size for that to 32MB. You do that by changing the highlighted ones (i.e., Image Flash Address) in file /JUNO/SITE1/HBI0262B/images.txt.
