Olimex PIC32-T795 support

RE: Olimex PIC32-T795 support
Hi Olimex,

I did all this things you told (like a wrote in Post33 above)

sold the jumper right and cut the wired Duinomite connection.

Called reinstalled 32MX795 BLoader´s with RST/BUT sequence.

No blinking Bootloader LED´s showed up.

Than i tried every BL .hex File i found in the net for PIC32MX795F512H
but till now no single one worked.

Did you or a other users ever tried to reprogramm the OLIMEX PIC32T795 from DUINOMITE to PINGUINO ?
If yes and it worked correct, so please let me know and send me the BOOTLOADER .hex file direct to my Email adress or give me the exact LINK to download it.

I think it is still a conflict between BLoader and connected LED´s and BUT Switch on this OLIMEX PIC32-T795 Board.

thanks for your suggestions in advance
and hopefully i get this board changed to PINGUINO mode this yearSad

Hey,

I played a bit with the board today. It seemed some definitions in digitalw.c were not according to the T795H schematics.

So I attach a bootloader I compiled before and digitalw.c with different PIC32_PINGUINO_T795 port/pin masks (I don't guarantee all definitions are fully correct, since I was in a hurry, but the few pins I tested worked as expected). This means you have to replace the original digitalw.c in \p32\include\pinguino\core with the one I attach and make sure that in the board selector inside the Pinguino IDE you select PIC32_PINGUINO_T795. Also make sure you recompile your code.

I also attach a simple double blink example I used.

Tell me how it goes.

Best regards,
Lub/OLIMEX

Did this solve your problems?

Hey
I know the last post here is from 2013, but..
... where is the current bootloader for pinguino for pic32MX795F512H?
And which pin is LED and boot button?

RD0 : reset
RB15 : led1
RB12 : led2

RE: Olimex PIC32-T795 support
How to use that? What is the differnece between LED1 and LED2?

I have burned the bootloader and my device shows up just after MCLR reset as "USB Input Device".

RE: Olimex PIC32-T795 support
Microchip uses LED1 and LED2 to indicate the bootloader status.
LED1 and LED2 blinking alternatively means the bootloader is waiting for USB communication.
You might then upload a program on your board.
I don't have this Olimex PIC32-T795 board so I'm afraid I can't help you more.

RE: Olimex PIC32-T795 support
So the Pinguino is using "HID bootloader" here?
What should be the power consumption of pic32MX795F512H in idle in that t795 configuration?

All Pinguino 32 use HID bootloader. Pinguino 32MX2x0 use a Pinguino version, the rest use a Microchip version.
I chose to stick to a Bulk version for Pinguino 8 because of the RAM/Flash size. However there is a HID version of the Pinguino bootloader for them too.
You'll find info. about consumption in idle state in the datasheet of the PIC32MX795. It also depends on how Olimex build this board. Please contact them for more information.
