Part Number: RM57L843
Other Parts Discussed in Thread: TMS570LC4357

Hi,

I found the inconsistency between user's guide and source code about GPIO diagnostic library on RM57Lx MCU.

Can you confirm which one is right?

Hi,

The doucment shows no diagnostic library is for RM57Lx GPIO selftest, but the source code shows it has.

Hi Shenruming,

It is document mistake,

Yes, GIO1A and GIO1B functions are also available in RM57Lx and TMS570LC43x devices too.

Thanks & regards,
Jagadish.

Hi Jagadish,

Thanks for your fast reply. But the sole macro definition representing test type of GPIO is not defined for RM57Lx.

Can you help check it?

Hi Jagadish,

Can you please help check whether diagnostic library function SL_SelfTest_GIO is available on RM57Lx devices?

The source code shows the applicable models do not include RM57.

Hi Shenruming,

One customer did analog loopback test using SL_SelfTest_GIO function for TMS570LC4357 and it worked.

So, i think it should work for RM57 as well.

Can you please try to verify by uncommenting the code.

Thanks & regards,
Jagadish.
