Runtime Instrumentation Testing - N1SDP
|
|
=======================================
|
|
|
|
For this test we used the N1 System Development Platform (`N1SDP`_), which
|
|
contains an SoC consisting of two dual-core Arm N1 clusters.
|
|
|
|
The following source trees were used:
|
|
|
|
- `TF-A v2.13-rc0`_
|
|
- `TFTF v2.13-rc0`_
|
|
|
|
Please see the Runtime Instrumentation :ref:`Testing Methodology
|
|
<Runtime Instrumentation Methodology>` page for more details. The tests were ran
|
|
using the
|
|
`tf-psci-lava-instr/n1sdp-runtime-instrumentation,n1sdp-runtime-instrumentation:n1sdp-fip.tftf-firmware`
|
|
configuration in CI.
