Tiny Core Base > Release Candidate Testing
Core v7.0beta3
Juanito:
Please go ahead and submit them for tc-7.x with a note in the info file that they are for testing.
andyj:
In submitqc line 240 the test for version 6 needs to be updated for version 6+.

lately while on the road I've been investigating why wifi drivers disconnect from AP's
I'm currently using tc-7b3
I'm not 100% sure where this error originates, be it the device driver or the kernel. May not be related to the original disconnects but I've noticed driver's have difficulty in loading it's desired firmware file is not located at /lib/firmware yet to resolve the issue an alternative method is used.
notice the direct loading error and resolution if loaded from /usr/local/lib/firmware/

however if I re-create the extension where firmware is installed to /usr/lib/firmware, then firmware is directly loaded successfully

Is this of any concern to us? or has the effectiveness of the driver changed because of this?
dentonlt:
Maybe this is off-topic, but it seems relevant enough.
I do a kernel rebuild to drop modules I don't need and put the ones I need into the kernel. That's not a problem.
If I build the 4.2.9 kernel on TC 6.4/x86_64, I get a 5mb bzImage.
The same build/config/scripts on TC 7.0beta3/x86_64 gives me an 8.5mb bzImage.
I wouldn't normally care ... but that's 60% change. Same build config, same scripts. Should a different gcc make that big a difference?

Juanito:
Which version of gcc?
Did you gzip/advdef the kernel modules?
