Part Number: TMS320F280049

Hello,
customer watches the CLA application RAM in the memory window. He sees that in some location it is writen with 0x0000s. What is the reason?

Holger,

There is not enough information in your post for me to guess why the locations are 0. Are other values expected? What is stored in this memory area? Is the program not working as expected?

Regards

Lori

Please refer to this FAQ:

http://processors.wiki.ti.com/index.php/Control_Law_Accelerator_(C2000_CLA)_Debug_on_CCS_FAQ#Q:_The_CLA_program_memory.2Fdisassembly_window_reads_back_all_0_while_the_CLA_is_executing._Why_is_this.3F

In this case not all of the accesses are blocked but many of them are. This is because of the priority of CLA opcode fetch over debug accesses.
