Hi, bought a SpokePOV kit, assembled, tested OK (power on LED run). Having problem loading image to it.
Host computer is Win XP Pro, SP2. Since I forgot to buy a serial dongle I made a parallel one.
I get the informative "Failed at address 0". I don't doubt I've screwed up, but I could use a hint. There's very little info on the web page as to what normal behavior and sequence of events is, precisely.
giveio is running; giveio_status says so; giveio_install claims sucess.
With the dongle plugged on, power-on-reset by removing a battery ("POR") doesn't run the LED sequence test. Dongle off, it does. Is this correct behavior? (I assume the microcontroller sees the host via dongle and waits for a command.)
I put a 'scope on the 4-wire interface:
** RESET remains high always (click WRITE, press switch)
** MOSI/SPI_IN stays high always
** SCK see pulses on click WRITE, no pulses on switch press
** MISO/SPI_OUT see pulses on switch press, no pulses on WRITE click
There seems to be specific static LED patterns with the dongle on (switch press changes it), could tell U which LEDs if it's diagnostic (as opposed to random
It's really not clear what I *am* supposed to see; precisely when and in what order I am supposed to do the following:
** power reset
** press switch
** click WRITE
ANy help appreciated... one week to go til BRC... I assume not enoug time to order and ship a serial dongle before next week!
