Part Number: AM625
Other Parts Discussed in Thread: SK-AM62
Hi experts,
My customer is evaluating am62x using SK-AM62. Could you tell me about the access operation to DDR using PRU?
They would like to transfer data from the am62x PRU to DDR, but is it possible to transfer data to DDR using the following constants?
DDR16SS0_SDRAM address:0x80000000
DDR address 0x80000000 is defined as reserved in C17 in the ConstantTable of the PRU.
In am335x, it was possible to transfer data to DDR using C31 in the ConstantTable.
DDR : org = 0x80000000 len = 0x00010000 CREGISTER=31
The memory map is based on the following information.
- pru software support package 6.1.0
- AM62x:pru-software-support-package-6.1.0\examples\am62x\PRU_Halt\AM62x_PRU0.cmd
- AM335x:pru-software-support-package-6.1.0\examples\am335x\PRU_Halt\AM335x_PRU.cmd

If you have any information on how to transfer data to am62x, or if you have any samples, we would appreciate it if you could share them with us.
Best regards,
O.H
