Propeller Start-up
Hi,
I have just received 2 prop chips and I do not have the clip so I have tried the alternative circuits posted with no success. I have a 4Mhz xtal connected, reset at +3.3v and BOE at Gnd and no connection to host. On power -up after a while should I not see a pulse train on pins 38,37 as the chip searches for a 24lc256 eeprom based on the boot-up sequence. Or in the absence of a host connection what connections on RST and BOE that would allow me to see this sequence so that I can ascertain that the chip is still good!
Thanks
Chris
