Best way to Flash the M4 from Linux

[Niklas Voi]

Hi,

i build a yocto and now my goal is to flash the M4 from the yocto system. I tried with echo to the Proc system but geht the following Error. Are there any hint to flash the m4? Is there a better tool for do it?

[88303.356298] remoteproc remoteproc0: powering up m4

[88303.359833] remoteproc remoteproc0: Direct firmware load for ./OpenAMP_TTY_echo.elf failed with error -2

[88303.369746] remoteproc remoteproc0: request_firmware failed: -2

[88303.375106] remoteproc remoteproc0: Boot failed: -2

many thx to everbody and best regards
