[Cbe-oss-dev] Invalid machine code

[Oliver Stolpe]

Hello group,

I have an issue programming the cell with the SDK. There is a error 
message I can't interpret. What does a "invalid machine code" error mean?

I get this error in conjunction with mfc_write_tag_mask. He writes the 
tag mask correct several times after a dma transfer. But exactly after 
the 13th transfer, during the 14th, it crashes with this error message 
when executing this function.

Any ideas?

Thanks in advance and best regards,
Oliver
