Hi Folks,
does anybody know how to use firmdl.c under Windows95 ?
I compiled it using cygwin32-b19, and it allways hangs in the rcx_send function
in the first read-statement, when trying to get the echo back from the RCX.
Looks like read is blocking, until some data arrives/the buffer is totally
filled !
I changed the read-call to get the data byte by byte, by reducing the number of
bytes to be read to a maximum of one, and doing the select before each byte.
After having received differing amounts of Data (18-24 byte), even though
select does not deliver a timeout, read hangs again, so select must have lied
about data being present at the serial port !
Don't know what to do about that !
Deleting the old firmware (which is done by the previous write) works, at least
my RCX-display looks like it worked.
Any ideas ???
Sven

| I don't know about firmdl, but there's a firmware download utility as part of the rcxutil package for nqcc. Just grab the windows version of rcxutil for the executable, or grab the main source distribution if you want to build it yourself. Here's (...) (26 years ago, 2-Dec-98, to lugnet.robotics)
