Part Number: DRA744

HI,

I am looking for  input/reference  related to diagnostic library to test the HW(DRA74X) on QNX 6.5.

I want to run self test for 

1. HW Integrity
2. RAM
3. Flash
4. CPU
5. Drivers

Please let us know where I can get relevant reference/document. 

Regards,

    Hi Amit,

    I have forwarded your question to a QNX expert.

    Hi Amit,

    There is not a single library or test tool that looks after all of these points. It is up to the user to put together such a package. The QNX BSP for DRA74x comes with a User guide on usage of the S/W drivers in the BSP.

    1) H/W integrity. Many of the S/W drivers included in the QNX BSP will include a loop back or test mode that can be run. Futher information on what modules you want to test are required to mprovide a more detailed answer. Texas instruments provides a Starterware package that has many test examples, that can be ported to QNX.

    2) RAM. The IPL section of the QNX BSPs include a memory tester that can be run. For memory performance any of the publically available benchmarks can be ported to QNX and/or QNX can be contacted for benchmark numbers on QNX.

    3) Flash. Flash drivers are supported by the QNX BSP, and testing can be as simple as running the 'dd' command. For integrity tests, write / read with checksums can be implemented. Performance is best measured transferring the data or running the use case that will be used in production.

    3) CPU. For diagnostics and/or selftest, please provide further detail. For CPU performance any of the publically available benchmarks can be ported to QNX and/or QNX can be contacted for benchmark numbers on QNX.

    4) The QNX drivers in the BSP often require a test application to drive them. For example the USB module and associated S/W driver could be tested with Bonnie, or could be tested copying a file from RAM to a USB Key. Please provide further details.

    Regards,
