hello friends !!!
i provided a few bluetooth articles related to linvor based bt-modules :)
now i need your help ... i'm and arm7 hw / fw guy and new to the atmega328p TQFP32
i have designed a custom avr board and 3rd party firmware for it and try to load it using the serial channel with a provided bootloader GUI. the tool times out. i verified that the RxD signal reaches the CPU. the design does not have a designated debug connection setup like spi and reset sigs.
now i have the following questions.
i used a PBRC14.74MR50X000 ceramic resonator as the clock source, but see no clock signal on either clock pins upon power-up of a non programmed (new blank) cpu. am i supposed to see my 14.74 MHz clock signal even a blank cpu is on the board, assumed to run off the internal 8 MHz / 8 RC clock and maybe the ext osc is still disabled. sorry, i didn't read all the 100s of avr user manual pages.
does a, from digikey or mouser bought, atmega 328p contain any sort of factory bootloader.
if yes, what bootloader GUI front-end for either windows or linux is available to download the hex image. (i do not need to change fuses, the hex file works on an original board, not the one with my additional I/O hardware).
if any of the above failed, what's the Atmel approved sequence to get a hex image loaded into a new atmega 328p-au. regular production style firmware image load.
i really appreciate any help and will contribute again, once i get this board running with the bluetooth module and a simple android spp app ... more bluetooth docs and android source code samples to follow, but i need to get the image into this lovely cpu :)
tx, tx, tx and cheers blue2u
p.s i feel pretty blue right now :(
