N2HET1/ePWM/SPI/ module failure indicator at R4

Keyur Patel

Currently I am using TMS570LS3137AZW.

Along with main application code (R4 Code), I have N2HET1, N2HET1, ePWM, SPI all other module running parallel, so if In the case of such module (N2HET1/N2HET2/ePWM1/..etc ) failure/reset/error/hang, Is there any status register available at R4, which indicates which module cause failure and how ?

Keyur,

For some modules that have SRAM (Like the N2HET and the MibSPI) the RAM has parity protection and you can get an error signal if the RAM is corrupt.
But generally, you need to implement your own CPU tests to check the health of the peripherals as it pertains to your particular applicaiton.

It sounds like you check out the SafeTI page next. http://www.ti.com/ww/en/functional_safety/safeti/index.html?DCMP=safeti&HQS=safeti

You might also benefit from the Hitex safety kit for examples.

Because of the holidays, TI E2E™ design support forum responses will be delayed from Dec. 25 through Jan. 2. Thank you for your patience.
