Hi,
I've just tried to track down the SMSC driver problem which was recently
reported on this list. After the MMU allocates a block for a sent packet
in smc_send_packet() there is a FIXME comment in the sourcecode:
- when I add puts("x"); after this comment it works.
- when I remove it it hangs.
- when I add the content of the putx() function (the register
operations) to the same location it hangs.
- when I add a function containing the register operation and call this
function after the comment it hangs.
- when I add a function which calls the function from the last step it
works - this is the same constellation as with the puts() call.
All this looks like some kind of a memory management or stack problem
for me; perhaps anybody else has an idea what might go on?
Robert
