U-boot put binary file to iCPU and make VSC7385 unmanaged. However reset flush internal memory and iCPU stop. In this case bootlog looks like that: [ 2.989047] vsc73xx-platform ffb00000.switch: VSC7385 (rev: 2) switch found [ 2.996192] vsc73xx-platform ffb00000.switch: iCPU enabled boots from PI/SI, no external memory [ 3.005057] vsc73xx-platform ffb00000.switch: Chip seems to be out of control. Assert reset and try again. [ 3.045034] vsc73xx-platform ffb00000.switch: VSC7385 (rev: 2) switch found [ 3.052171] vsc73xx-platform ffb00000.switch: iCPU disabled, no external memory Best Regards, Pawel Dembicki
