Re: C8051F330 serial port programmer

Just got back from support with silabs.

for 330 uC, they have JTAG or c2 methods. documents (AN-127? & another
one) downloadable from their website.
as for c8051f121 or others, go JTAG.

JTAG means a whole lot of programming compared with rs232.

I don't like such a company without too much support for open source
people.

I've found some JTAG interfacing circuits for FPGA and I have an
Altera eva board with JTAG. When I got time I need to work out this
problem it wouldn't be too much difficult.

hey folks

how to build a simple serial port (rs232) programmer to burn the
C8051F330 by silicon lab?

I built programmer for TI microcontrollers but this is 1st time to use
C8051F uC.

The nice folks at Silabs have published the method for downloading on
the JTAG port. Rs232 is a an easy enough thing to read. You just
need to create a program in a micro of some type to translate. You
can buy just such a thing from them for less than it is likely to cost
you to build one.

Unfortunately Silabs didn't publish the debugging hooks of the micros
so you are stuck using their pod for the debugging purposes.

Also, the Silabs IDE only sort of works under "wine" so if you need to
debug code you either have to put your computer at risk by running the
virus-magnet OS or you have to live with a bunch of stuff not working.

There is a gnu project to reverse engineer the interface but it
doesn't seem to work. They took a path that I think is a dead end.
They used the gdb model for the user interface. Unfortunately gdb is
not the right model for debugging 8051 assembly language programs. It
is too bound to the ideas of debugging higher level stuff.
