Multiple HEX output file

decai wang

Hi,Sir!

I want to get multiple hex file, for example, a boot section is a standlone hex file, other user code is another hex file? how to set up in UV4?

    In fact, I use CY7C68013A in my project, when I select C2-load mode, hardware boot loader copy only 16K bytes in E2prom(24L256)into internal 16K XRAM and CODE space(0x0000~0x3fff). if code size is less than 16K Bytes, it is ok. but my code size is bigger than 16K bytes, so I have to make my project into two hex file, the code size of 1st hex file is less than 16K bytes(0x0000~0x3fff), the 2nd hex file is located from0x4000~0xDFFF(40K bytes).

    When the 1st code segment is loaded into internal 16K from I2C eeprom, FX2LP boots up and call TD_Init(), add my copy code:it will continue to read code data from eeprom and copy it into 0x4000~0xDFFF(movx inst).

    Of course,I attached one 64K SRAM with FX2LP, SRAM RD <---> FX2LP OE(RD and PSEN),SRAM CS <--->FX2LP CS. EA = 0. So, one unified space(0x4000~0xDFFF,XDATA and CODE) is added.

    I think this method can solve the bigger code code size case(>16K bytes) and can still work at C2 load mode.
