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:
1 2 3 4 5 6 | 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
1 2 3 4 5 6 | 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
.
