S32K324 Ram allocation problem

Jackson_Ping — Wed, 24 Jan 2024 02:51:36 GMT

Hi,all,

I am currently using the S32K324 chip,But I have some problems at the moment.

In the attachment of the S32K324 manual there is a file of memory allocation, where the size of SRAM0 and SRAM1 correspond to core 0 and core 1 respectively?Or does SRAM0 or SRAM1 of core 1 work?

My current situation is: the program is in core 0, and my SRAM 0 space is used up. Can I allocate more SRAM space by modifying the LD file? Take more SRAM1, for example.

Hello,

Yes, RAM is not linked to just one core. It sits on the bus common to both.

By modifying the linker you can allocate any RAM to core. Slaves on XBAR can be assigned to any master listed in reference manual.

Best regards,
