Instead, how about adding an argument to override the default behavior of running "cbmem -c" on the target so that the user can pass in a filename? The user will simply capture the serial output using whatever tool they like, dump the output to a text file, and run the script with an argument to use the file instead of calling "cbmem -c". Here is a proof-of-concept: http://review.coreboot.org/#/c/5191 . But in general I think I agree with Vladimir. CBMEM console should be supported and if not then that should be fixed. -- David Hendricks (dhendrix) Systems Software Engineer, Google Inc.
