Known issues on the Kaboard
|
|
===========================
|
|
|
|
Version 1.0
|
|
-----------
|
|
* TXD and RXD lines from ft232r to AVR are not crosslinked.
|
|
Correct is : ft232r TXD -> AVR RXD, ft232r RXD -> AVR TXD
|
|
|
|
Solution : Cut the tracks and use some wire or 0 Ohm resistors to fix it.
|
|
See photos/txd_rxd_1_0_fix.jpg for details.
|
|
|
|
Fixed in 1.1
|
|
|
|
* Reset is directly connected to the dtr pin on the ft232.
|
|
When programming the AVR via the isp header,
|
|
the porgrammer is unable to pull reset low for this reason.
|
|
Also when progamming via usb with avrdude dtr will stay low
|
|
to long time the bootloader won't start in time.
|
|
|
|
Solution : Cut the track on the backside of the board
|
|
and insert a 100nf capacitor.
|
|
See photos/reset_1_0_fix.jpg for details.

Fixed in 1.1

|
* Jumper settings table on back side is totally messed up.
|
|
|
|
Correct table : USB: JP2 open and JP3 short,
|
|
Selfpowered : JP2 short and JP3 open
|
|
|
|
Solution : Write a label and glue it over the faulty silkscreen
|
|
|
|
Fixed in 1.1.
