Newbie: Problem programming AT90CAN128 through STK500 board. - Rav - 02:26 13-06-07



Hi,

I have a custom made communication gateway PCB with an AT90CAN128
microcontroller. The PCB card has its own 6 PIN ISP interface that i
connect to the 6 PIN ISP of the STK500 board. The STK500 board is
connected to the PC through the standard RS232 programming port. I am
using AVR studio 4 to download the program onto the controller's flash
memory. When i try to access the controller's flash for
programming...it fails. The error says: 'Failed to enter the
programming mode'. I have check the pin configurations and
connections. Those seems to be ok. I wanted to ask whether the
procedure to program the controller in this way is right or
not? ...Plz help.
When I went through the STK500 manual, it says something about using
STK501 top module for the AT90CAN128. Please explain what this STK501
top module is or where can i find the relevent solution for it?

thanx and regards...
Ravi Pathak

The STK501 has a clamshell socket to hold a 64-pin chip. You don't need
it to use the STK500 on-board ISP.

Firstly, check which pins of the 128 you have connected to the ISP
connector and make sure it is PDI & PDO not MOSI & MISO.

Is there another device also connected to the PDI (PE0) pin? If so you
will need to isolate it from the ISP connector with a resistor. Usually
4k7 is fine. The ISP pin must be connected directly to the PDI pin on
the CAN128.

U r saying that the AT90CAN128 uses PDI/PDO for programming rather
than
MOSI/MISO..???

U doesn't post here anymore, nor does U r.  I.e. geekspeek is not
appropriate behaviour for Usenet.

RTFM, that's what data sheets are for.

From the way you write, I guess reading may be a problem.

My apologies for the way i presented my query. I didn't intend to ask
that way. I am very sorry about all the mess and assure it won't
happen in he future.

thanks
