Patch for additional serial speeds #17

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago

I can consistently get my boards to download at 921,600.

This patch adds in all the standard to 2,000,000.

The symptoms of going too fast are that it never initially connects. I have 
never had a corrupted download.

Please patch the w32 code for these rates too and I will commit this.

I would really like to patch and test the w32 code but I do not have a machine 
capable of even compiling.

The serial subsystem was designed well so that the rates could be partially 
implemented. I noticed already that the two serial implementations are 
different since w32 does has the 1800 commented out.

I attached a patch that has the new baud rates commented out for w32.

Excellent, thanks, I will apply this shortly, will see if we can get someone 
under linux to test these baud rates.

I can confirm that this patch seems to work. I was able to download code to my 
system at 460400.

In absence of the maintainer, I have set up a git repository where I will try 
to incorporate all outstanding patches: 
https://gitorious.org/stm32flash/stm32flash#more

I applied this patch in the issue10 branch. Please provide a name/address that 
I can use as commit author (and Tested-by: if possible).

I merged this into my "merging" branch and tested successfully reading from 
flash with 2000000 baud on Linux and 115200 baud on Windows 7, over a CP2102 
USB UART. That was quite a speed improvement, thanks!

This has now been fixed in the official repository and is included in version 
0.3beta2.
