TMS320F280039C: The alert 1173-D unknown attribute "noblocked" occur when compiling

I believe that attribute is only supported in C28x side. This is related to Data Page Pointers, which is a C28x Instructions set feature. For more details,

Hello Veena,

Thanks for your support and the docs.

After using this variable attribute, the linker can link correctly and eliminate the associated diagnostic alert, but a new alert: "Unknown attribute" appears.

According to spru514ydoc, this alert should not appear in normal use. The customer guesses may be it's due to the supported GCC supported or something else? How to eliminate this new alert?

Thanks and Regards,

Cherry

Hi Cherry,

Apologies for the delay.

Are you still facing the issue?

Hi Veena,

Yes, could you help give some updates?

Thanks and regards,

Are you using the attribute in a .cla file, or in a header file which is included in the .cla file?

As mentioned earlier, this attribute is not supported by CLA

It's in a header file which is included in the .cla file. This attribute is used to resolve alerts that occur with CLA defined variables.

If the header file contained in the CLA cannot use this attribute, does the previous alarm fail to remove? 

This is the previous alert which appears in CCSV12 regarding the CLA and the customer has reviewed the section 6.15.4 of  the docs then resolved it as follows:

Hi Veena,

May I know is there any updates at your end?

Best,

Hi,

Are these variables shared between C28x and CLA? In that case make sure they are defined in a .c file.
