TMS320F28379S: question about HWBIST

Huihuang Chen

Part Number: TMS320F28379S

Hi Champ,

From the F2837xS TRM , there have below description, could you advise the detail about the special boot ROM flow and HWBIST flow?

Thanks!

2.3.9 Hardware BIST Reset (HWBISTRS)
The Hardware Built-In Self-Test (HWBIST) module tests the functionality of the CPU. At the end of the
test, it resets the CPU to return it to a working state. This reset (HWBISTRS) only affects the CPU itself.
The peripherals and system control remain as previously configured. The CPU state is restored in
software as part of a special boot ROM flow. For more information on the HWBIST flow, contact your local
TI representative.

Hi,

In case of HWBIST reset, device boot normally. There are some status bits which get cleared in bootrom. As mentioned in last statement, for more detail on this you need to contact local TI representative.

Regards,

Vivek Singh

Hi Chen,

Sorry for the late response.

Can you please check if topic "2.2 Managing HWBIST on Dual-Core Device" from "C2000™ Hardware Built-In Self-Test" App note (SPRACA7) addresses your question?
