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?
