Hi, I'm programming for a Cypress EZ-USB FX2 platform, and I'm adding onto the default firmware. I'm having some problems compiling some code, and I'm wondering if I'm running into space limitations already.
First of all, I get warnings when I try to initialize the I2C interface by calling
EZUSB_InitI2C();
I get the warning message
*** WARNING L16: UNCALLED FUNCTION, IGNORED FOR OVERLAY PROCESS NAME: _EZUSB_WAITFOREEPROMWRITE/I2C *** WARNING L16: UNCALLED FUNCTION, IGNORED FOR OVERLAY PROCESS NAME: _EZUSB_WRITEI2C_?I2C *** WARNING L16: UNCALLED FUNCTION, IGNORED FOR OVERLAY PROCESS NAME: _EZUSB_READI2C_?I2C Program Size: data=112.4 xdata=6830 const=216 code=8870
Next, when I try to add in another for loop as below
for (i=0;i<16;i++) EZUSB_ReadI2C(ZTBL_ADDR+i, 0x01, z_table[i]);
I am unable to compile. I get the following error messages on top of the warning message
*** ERROR L107: ADDRESS SPACE OVERFLOW SPACE: CODE SEGMENT: ?L?COM001A LENGTH: 00000BH *** ERROR L107: ADDRESS SPACE OVERFLOW SPACE: CODE SEGMENT: ?L?COM0022 LENGTH: 000009H *** ERROR L138: CODE GENERATION: PROBLEM WHEN PROCESSING INSTRUCTIONS CAUSE: JUMP TARGET OUT OF RANGE ADDRESS: 0750H *** ERROR L138: CODE GENERATION: PROBLEM WHEN PROCESSING INSTRUCTIONS CAUSE: JUMP TARGET OUT OF RANGE ADDRESS: 0761H *** ERROR L138: CODE GENERATION: PROBLEM WHEN PROCESSING INSTRUCTIONS CAUSE: JUMP TARGET OUT OF RANGE ADDRESS: 0785H *** ERROR L138: CODE GENERATION: PROBLEM WHEN PROCESSING INSTRUCTIONS CAUSE: JUMP TARGET OUT OF RANGE ADDRESS: 07B0H Program Size: data=112.4 xdata=6830 const=216 code=8993 Target not created
Have I run out of space already?
Thanks!

"The chip I'm using(CY7C68013) has 16KB internal RAM. How can I increase the XDATA/CODE spaces?"
Do you understand the distinction between CODE and XDATA in the 8051 architecture?
Does this chip allow that 16K of RAM to be used as CODE space?
"still don't know where to change the values(which file or menu dialog?)"
So start here: http://www.keil.com/support/man/docs/uv3/uv3_examples.htm - it walks you through the whole process of creating a project, setting options, and debugging...
