hi,

recently i use 24bit eeprom as bootloader. However, after i write the bin file to eeprom , the code can not work successfully. but in debug mode the code can work.

here my questions:

1.what is the correct dos command line to create a bin?

2.in the program i use bios , if there is some special requirements about bios bin file (small large or huge)?

3.in debug mode ,i use gel file , but when i delete gel the debug mode cannot work neither. if there is some notes about gel file?

thank you for everyone~

    hi,

     

    1. hex55.exe -boot -v5505 -serial8 -b input.out -o .output.bin (example)  Details are in http://focus.ti.com/lit/an/sprabd7/sprabd7.pdf

    2. You can use "huge" for C5515.There are no specials. Just match the same memory model for all your code including a library.

    3. If you read through, you can recognize what is in there. You'd better making it work without gel file than use flash.

    You need to add PLL configuration and other initialization of peripherals.
