INITNAND gets stuck

Hello there.

Please help, this is so frustrating.

I connected NAND module S34ML04G200TFI000 ( to the breakout board, according to the datasheets and to the dev board schematics.

Removed all the other devices, other than UART. Pulled up NAND CE, because datasheet says it should by UP during boot. Pulled up NAND WP.
Powered NAND from IOVDD.

When I run INITNAND.BAT, it displays these lines and then hangs. There is no more output.

VSEMU 2.2 Nov 12 2010 16:48:42(c)1995-2010 VLSI Solution Oy
Using serial port 3, COM speed 115200
Waiting for a connection to the board...

Caused interrupt

I am attaching connection schematics.

Can anyone advice what I am doing wrong? Did I forget some PIN? Should I pull something else up or down? Does anything on breakout board orevent it from working?
Is there any way to diagnose this?

Thanks in advance

How's your NFRDY signal? If Chip Select is high and Ready is low, the hardware gets stuck waiting for the nand flash to become ready.

For anyone reading this:

Removed my program and all the drivers, rebooted. InitNAND works like a charm.

It may or may not be obvious.

Dear Panu

Sorry about bothering you with the problems I can solve myself.

Recap in case someone else is wondering:
After successfully running InitNAND you need to format NAND.
The solution is here: viewtopic.php?f=13&t=1664&p=8213&hilit= ... nand#p8213.

1) put K9F4G S in section [5] of config.txt (it seems important that the drive letter is S!)
2) Boot board with high GPIO0_0 and GPIO0_1.

Thanks again.
