If you flip to the internal data memory area of the section, you will see that RAM 0 to 127 is addressed directly and indirectly as in the 80C51 (DATA or IDATA). RAM 128 to 255 is addressed indirectly as in the 80C51 (IDATA). The additional 256 bytes of RAM is called AUX-RAM (0...
Friends, I'm running sdcc for 8051 in small mode. When compiling the file, I'm getting the following error: ?ASlink-Error-Could not get 10 consecutive bytes in internal RAM for area OSEG. The memory map is as follows: 0 1 2 3 4 5 6 7 8 9 A B C D E F 0x00:|0|0|0|0|...
Instead, specify the memory regions of your application directly as memory classes in the µVision dialog page Project - Options for Target - LX51 Locate as described below: Disable: Use Memory Layout from Target Dialog User Classes: EDATA (0x7F0000-0x7F04FF), /* on-chip RAM */ HCONST...
