Re: cmd file of Harvard architecture

Dear Friend , It seems your DSP have not any internal Flash , so if you want to use Flash memory , you have to connect an external Flash Chip to External Interface of DSP. If you see the memory map of your DSP , it seems there is unique ID range ( 0x0180 0000 to 0x 0183 FFFF ) . So every memory loca...

Re: A trouble with JDM programmer

Microcontroller taking clock pulses , from our external Crystal , only if we select XT.
