Posted on May 17, 2011 at 11:58Hello all,
I‘m using uPSD3334DV device in my target ( the power supply is 3.3V ).
When I run my program on the evaluation board ( Turbo uPSD DK3300 ) the program run OK and there is no problem.
But when I run my program on the target there are problems. The program jump to unexpected Address.
I try many hardware-mapping configurations to solve this problem and nothing helps.
I write a small program that initialize array of 1000 elements and after that change I/O bit.
1- xdata PSD_REGS PSD8xx_reg _at_ PSD_REG_ADDR;
2- PSD8xx_reg.DIRECTION_B |= 0x10 ;
3- void main( void )
4 - {
5- EA = 0;
6- for (Index = 0 ; Index < 1000 ; Index ++ )
7- DataArray[Index]= 0 ;
8 - while ( Forever )
9 - {
10 - PSD8xx_reg.DATAOUT_B ^= 0x10 ;
11- }
12- } // main
When I mask only line 10 the program don’t jump to unexpected Address.
When I mask line 6 and 7 and line 10 work, the program also don’t jump to unexpected Address.

I attached the orcad schematic and soft expreess design
Please, somebody can kindly help me ?
