Hi Shivasharan,

Thank you for your reply. Since there are some different descriptions in TRM, Datasheet and App note, I'd like you to confirm it.

Could you make sure whether R5F has L2 RAM (or Cache) or not ?

Yes? or No?   This is very important for the customer and us also to choose the device.

Thanks and regards,

Hi,

 Yes, AM243x has 64KB L2 RAM (TCM) per core with ECC. Please refer to : 3.1.3 Cortex-R5 Memory Access Latency section in https://www.ti.com/lit/an/spracv1a/spracv1a.pdf if customer is looking for any specific data.

Best Regards, Shiv

Hi Shivasharan,

Thank you for your answer. Does L2 RAM mean TCM ?  Since TCM can be operated with no wait cycle, I thought it's Level 1. OK, understood.

Thanks and regards,
