The SPRA755A (Getting Started in C and Assembly Code With the
TMS320LF240x DSP) application note from TI and example project
with it.

I load gel file comes with example project.
I load .mak file in the project.
Build All-> 0 errors, 0 warnings. It's ok.

I select load program example.out from menu:
-CPU-DSP Device Driver-
Trouble Writing Target DSP Memory
Error Number -2052
Error address 44
Memory Map Error : Range

Retry/Cancel

Selected cmd file is here. What's wrong? If it is something
about Memory Map from Options menu, what should be the correct
memory settings?

My CCS is in "C2xx Simulator" mode. And a item called "CPU" appears
as sub-item in Code Composer Setup. //p.s. no evm or dsk plugged.

Is there LF24xx specific DVR Driver files or CCS configuration
files? If so, please send me.

Greetz.

• I have the chips now.(LF2407A and 2403). What is the base configuration.... — Sobakava   (30.01.2003 15:32, 280 байт)
  • You need a DSP, MAX232-like RS232 level translator, power supervisor and quartz crystal. That's all. — SM   (30.01.2003 23:09, пустое)
    • What kind of power supervisor? Is there a 3.3V MAX232 like chip? — Sobakava1   (31.01.2003 01:42, пустое)
      • I use TPS3707-33 supervisor. But you can use any 3.3v powered. About 3.3v max232 - later, i don't have access to datasheets now. — SM   (31.01.2003 09:41, пустое)
• Execute the following GEL file, then use "Memory maps" menu before loading: (+) — SM   (29.01.2003 11:59, 1572 байт)

        • May be another GEL file is loaded? With function, that resets memory map when file being loaded? — SM   (29.01.2003 12:58, пустое)
