I am using P89V51RD2 chip from NXP which has ... 1Kb of RAM Note that's the sum total of all the RAM on the chip- it's not one contiguous block of RAM. Specifically, in Keil, DATA refers to the 128-byte directly-addressable memory space. Is there any compiler settings by which I can increase the Data Segment Size? No - it is fixed by the hardware architecture. http://www.danlhenry.com/mfg/phili...ARCH_1.pdf - specifically, pp 1-3 http://www.danlhenry.com/mfg/phili...WARE_1.pdf http://www.danlhenry.com/mfg/phili...UIDE_1.pdf Or any other method to resolve this error Move stuff out of DATA and into other (IDATA, XDATA/PDATA) address spaces... http://www.keil.com/support/m...mareas.htm |
