Support for PIC32MX270

Support for PIC32MX270
Hi.

Is there support for the PIC32MX270?
If not, how to add it?

Especially the PIC32MX270F256B would be interesting, because it is a direct replacement for the PIC32MX250F128B (both DIP28), just double the size of flash and RAM.

Cheers,
Uhrheber

I received samples some weeks ago and I now try to compile a bootloader for this proc.

It is easier to complain than it is to do, but it is better to do than it is to complain.

Hello,

is it possible to download the bootloader for PIC32MX270?

Regards,

RE: Support for PIC32MX270
Yes it's possible but I found it doesn't work properly Confused .
I've already added support of the 270 to the IDE and I will add a clean bootloader on github as soon as possible.
Please stay tuned here, on our Twitter channel or on the Blog for updates.

RE: Support for PIC32MX270
Hello to all!
i like use 32mhz crystal for my pinguino pic32mx270f256b.
There is a bootloader ready for this freq.?
Or is a big deal change boot loader to run on 32mhz?

Thank you for support!

RE: Support for PIC32MX270
For all people who want to change the bootloader supported crystal frequency :
The source code is here.
Take a look at config.h and change the DEVCFG2 bits.
Take care there are 2 definitions, one if you compile the code with MPLAB, the second if you use the Pinguino GCC Toolchain.

Note1 : PLL must be 4MHz so make sure your Crystal frequency / FPLLIDIV = 4MHz.
Note2 : 32MHz crystal implies FPLLDIV = DIV_8 which DOES NOT EXIST, values available are :

DEVCFG2: DEVICE CONFIGURATION WORD 2
bit 2-0 FPLLIDIV<2:0>: PLL Input Divider bits

111 = 12x divider
110 = 10x divider
101 = 6x divider
100 = 5x divider
011 = 4x divider
010 = 3x divider
001 = 2x divider
000 = 1x divider

So valid crystal frequencies (to use the USB HID Bootloader) are :
111 = 12x divider => 48MHz

110 = 10x divider => 40MHz
101 = 6x divider   => 24Mhz
100 = 5x divider   => 20MHz
011 = 4x divider   => 16MHz
010 = 3x divider   => 12MHz
001 = 2x divider   => 8MHz
000 = 1x divider   => 4MHz

RE: Support for PIC32MX270
ok thank you!

i think i will not use my 32mhz crystall Smile

i'm new to pic32

if i'm not wrong with default pinguino boot looader and 8mhz crystal , pic32mx270f256b will run core at 40 mhz, right?

there is a internal 8mhz osc bootloader hex?

i like try my pic with out crystal (and waiting for new 8mhz crystal)


thank you for support Smile
