Hello,

ARM describes pld assembler instruction:

"PLD (Preload Data) signals the memory system that memory accesses from a specified address are likely in

the near future. ..."

It's implemented in ARM 5TE and above, and iMX23 ist ARM 5TE.

On my system, pld instruction seems to execute as nop. Is it available?

Regards,

Rolf

The MX233 uses ARM926EJS core, therefore read ARM Information Center and in particular, quote:

  • The PLD data preload instruction does not cause data cache linefills. It is treated as a NOP instruction.

Thank you very much.

Not the answer I wished, but I have to handle without pld.

Regards,

Rolf
