DRAM zeroed out by fpga-clear-local-image?

0

Hi, our application relies on DRAM being cleared (zeroed out) before starting execution on the FPGA. So far, we've been manually zeroing out DRAM through our own mechanism, but I noticed that the description of fpga-clear-local-image states that it "Clears the specified FPGA image slot, including FPGA internal and external memories that are used by the slot."

Does this mean that if we do fpga-clear-local-image followed by an fpga-load-local-image, we can rely on DRAM being zeroed out when the AGFI we load starts running?

Relatedly, can we also rely on URAMs being zeroed out when going through the same process (clear then load)?

Hello,

The DRAM is guaranteed to be "cleared out", which means the contents will be wiped, but this does not guarantee the data is zero. UltraRAM is initialized to 0 on CL load (note no clear is needed).

Thanks,
