Grazie mille Cristian for this new release and for all the effort you have put into during all these weeks!

The interrupt hooks for Due are great!  Now RTOS ports run with no mods to Arduino 1.5.2.  I will soon post 1.5.2 updates for all RTOS ports.

Now the not so good news for AVR.  The new malloc() does not work in threads unless their stack is above the heap.

Here is the gotcha in malloc:

Code:

cp = STACK_POINTER() - __MALLOC_MARGIN__;
if (cp <= __brkval)
 /*
  * Memory exhausted.
  */
 return 0;

If the stack pointer is below the heap, malloc() fails.

Personally I think this is a good thing.  It enforces the embedded systems rule, "dynamic memory shall not be used after setup".

Due to its risk, dynamic memory allocation is forbidden, under the DO-178B standard, in safety-critical embedded avionics code.

Hello Cristian,
For the new CAN API, the following lines should be added to variant.h

Code:

/*
 * Complementary CAN pins
 */
static const uint8_t CAN1RX = 88;
static const uint8_t CAN1TX = 89;

// CAN0
#define PINS_CAN0            (90u)
// CAN1
#define PINS_CAN1            (91u)

Regards, Wilfredo

The verbose output for the Uno upload is not being honored. The IDE and the preferences.txt file are set correctly. However, it is working in the Due.

I don't know if this normal but my arduino mega 1280 serial port ID cannot be seen from IDE's Tools/SerialPort so impossible to download any sketch.

NOT fixed on my PC (Native port, W7SP1x64).

[Reply #8 on:]

You may have old Native port USB core code on the Due, which can cause the BSOD.  Try uploading a basic sketch (with the new IDE) via the Due Programming port first.  This should update the Native port USB core code on the Due.  Then try again connecting to the Due Native port on your PC.

hm looks like I can't upload to mega 2560, is it just me?

I've tested both my mega 2560 rev 2 and rev 3, uploading works.

Now as posted before, mega 1280 does not upload because IDE can't find its USB port !
