3.8. BIST Safety Example¶
3.8.1. Introduction¶
This example demonstrates usage of the SDL PBIST and LBIST APIs to check the status of the Power-On Self Test (POST), as well as to perform software-initiated PBIST and LBIST tests for the varoius controllers on the device. The example shows performing the BIST checks in stages, similar to how a boot application might perform PBIST and LBIST while booting the cores at startup. The test is executed from the MCU R5F core and does not use an OS.
The following controllers are tested in the associated phases.
Pre-stage:
HWPOST results are checked and reported
PBIST Negative and positive tests for Main Infra and MSMC are executed
Phase #0:
PBIST Negative and positive tests for Main Pulsar 0
LBIST test for Main Pulsar 0
Phase #1:
PBIST Negative and positive tests for Main Pulsar 1, C7x, C66x, VPAC and DMPAC
LBIST test for Main Pulsar 1, C7x, VPAC, DMPAC
Phase #2:
PBIST Negative and positive tests for A72, HC, Encoder and Decoder
LBIST test for A72
When executing PBIST in the example application, the test-for-diagnostic (negative test) is executed first, followed by the PBIST test itself. At the end of the test, the result for each test is printed.
3.8.2. Example Details¶
The example should be loaded to the hardware using the Secondary Boot Loader (SBL) from the SDK.
