I am having similar issues but I cant get my pin 2 of port B to simply go high. I followed your help and thansk for pointing out the utility.l

I found it:

SCLKB (used by serial flash on RCM5750/RCM5760 and RCM6700 family.)
Due to serial boot flash requirements, the RCM6700 familys edge connector
pin 27 (PB0 / SCLKB) must not be used for general purpose I/O. Although
reserved for SCLKB only, this usage may be shared with an off-minicore SPI
device.

1. Goto C:\DCRABBIT_XX.XX\Utilities, then open IOConfig.exe.
2 Change your IO On "Parallel Ports Pin Assignments according to your needs.
3 Klik File - Save Library- typo C:\DCRABBIT_XX.XX\LIB\Rabbit4000\mylibrary.lib in "Library File Pathname"
4. Open mylibrary.lib C:\DCRABBIT_XX.XX\LIB\Rabbit4000 used Dynamic C and see this line:

void BoardInit()
{
// ClockCheck();
// The following differ from BIOS settings
WrPortI(PBDDR,&PBDDRShadow,0xFF); // Port B Input and output Pins
WrPortI(PCDDR,&PCDDRShadow,0xFF); // Port C Input and output Pins
WrPortI(PCFR,&PCFRShadow,0x00); // Port C Input and output Pins
WrPortI(SPCR,&SPCRShadow,0x84); // Port A Input and output Pins
}

5. Open your program from Dynamic C IDE add as follows:

//////////////////////////////////////////////////////////////////////

#use "rcm57xx.lib"
//#use "mylibrary.lib"; // call mylibrary.lib from here OR paste code direct in code

main()
{
int i;

brdInit(); // Press for view this settings
// Select brdInit in "C:\DCRABBIT_10.56\LIB\RABBIT4000\RCM5XXX\RCM57XX.LIB" then
// press Ok, you will see the default settings for your board in here
// Click View Source for edit RCM57xx.LIB you can change the library or directly here but I do not advise it.
// Change library from mylibrary.lib or direct paste as follows:

// paste your config in here
WrPortI(PBDDR,&PBDDRShadow,0xFF); // Port B Input and output Pins
WrPortI(PCDDR,&PCDDRShadow,0xFF); // Port C Input and output Pins
WrPortI(PCFR,&PCFRShadow,0x00); // Port C Input and output Pins
WrPortI(SPCR,&SPCRShadow,0x84); // Port A Input and output Pins

//WrPortI(SPCR, NULL, 0x84); // Port A as output
//WrPortI(PBDDR, &PBDDRShadow, 0xff); // Port B as output
//WrPortI(PBDDR, &PBDDRShadow, 0xff); // Port C as output
while(1)
{
// add your programs in here

//WrPortI(PADR, &PADRShadow,i);
//WrPortI(PBDR, &PBDRShadow,i);
//WrPortI(PCDR, &PCDRShadow,i++);
}

}

Hi to all of you,

What is wrong in my 10 line of code, Not all pine toggle

main()
{
int i;

WrPortI(SPCR, NULL, 0x84); // Port A as output
WrPortI(PBDDR, &PBDDRShadow, 0xff); // Port B as output
WrPortI(PBDDR, &PBDDRShadow, 0xff); // Port C as output
while(1)
{
WrPortI(PADR, &PADRShadow,i);
WrPortI(PBDR, &PBDRShadow,i);
WrPortI(PCDR, &PCDRShadow,i++);
}
}

Don't the minicore modules use PB0 as the clock on the serial flash? Check PBFR to see if it's an alternate output.

Not work, when DC is programming flash PB0 give data, but as soon the code
start there is nothing on PB0 and DC give error "while debugging timeout"

Any Clue?

#define BYTE_OFF 0xFF
