QUERY : newlib for STR710 and GNUARM for STR710

hello:

is there a port of newlib for the STR710?
where can i find it?

what platforms are supported by GNUARM's
newlib? will it work on the STR710?

thank you for the information,

Aaron

AFAIK STM STR7 are ARM7TDMI cpus, so gcc and newlib will work for them.
 From the compiler point of view there's no difference between ARM 
cpus if the core is the same.

GNUARM (gcc + newlib) supports ARM7TDMI core, so I suppose it can work 
even on STR7 devices.

You can download a free version of the Raisonance IDE (RIDE) from
the raisonance site. It comes with a gnuarm and some extra header
files and library code to help one to quickly get going on the ST ARMs
as well as the new ST Cortex devices.

hello Francesco:

sorry for the long delay in replying.

yes, but if i have to printf to the console that is connected to a UART,
wouldn't i need to do some STR71 specific programming?

how would GNUARM's newlib be able to use printf to send characters to
the STR710's UART?

i can understand how ARM7 only code will work, of course.

yes, it will, i understand. however, what about the STR710 specific
parts such as those that enable printf to send data to UART console?

that's why i wanted to know if someone has a ready newlib for STR710.

Often, to use printf() in an embedded application you'll just need to
write a putchar() that outputs a single char to your target device:
LCD, serial port, FIFO queue, etc. Typically there's a stub for
putchar() in the library; the new putchar() included in the
application code will then be linked in place of the stub and used by
printf().

Notwithstanding Rich's good advice, if you really want to get the full 
newlib implementation you need to implement a set of stub functions.  
I've done that for the LPC (NXP) series 
http://www.aeolusdevelopment.com/Articles/download.html You could easily 
do the same for the STR7.
