Compiler/TMS320F280049: How to access byte peripheral LIN via CLA?

StephanS

Part Number: TMS320F280049

Tool/software: TI C/C++ Compiler

Hi,

from the datasheet, the 280049 type 2 CLA should be able to access the LIN module.

This however is byte-addressable. The bp_16 and bp_32 typedefs via byte_peripheral attribute are rejected by the compiler.

So how to access the LIN from CLA?

Hi Stephan,

I will have to check with the experts here at TI and get back to you by early next week.

Hi Stephan,

Yes, just got an update this morning from SW team.

Typedefs bp_16 and bp_32 are not supported on CLA, they are only meant for C28x. Instead you can do access as follows:

HWREGH(base + offset) for lower 16-bit and HWREGH(base + offset + 2) for upper 16-bit.

Hi Nirav,

thanks for the info.
This is exactly as we did the access (for the 28075) until TI presented the bp_16 and bp_32 solution.
The problem is that we now cannot use the TI provided header files which contain bp_16 and bp_32 when using LIN on the CLA.
We can use them on the CPU, but have to use different ones on the CLA.
Not very convenient.
Any plans to support bp_16 and bp_32 on the CLA?

Regards,
Stephan

Hi Stephan,

I understand, let me check with our SW team and if needed will raise a ticket to get that support added for next release.

Thanks & Regards,
