Re: [Openocd-development] During nand flash writing OCD crashes with Hitex LPC3250-Stick

I will provide one if it works reliably.

Anyway do you know why there is so big timing differences accessing large
page nand flash with slc or mlc mode?

With mlc mode accessing is fast:
> lpc3180 select 0 mlc
mlc controller selected
> nand probe 0
NAND flash device 'NAND 128MiB 3,3V 8-bit' found
> nand dump 0 /mnt/share/nfOcd0x80000dd.img 0x80000 0x4000
dumped 16384 bytes in 9.658648s (1.657 kb/s)

With slc mode accessing is very slow:
> lpc3180 select 0 slc
slc controller selected
> nand probe 0
NAND flash device 'NAND 128MiB 3,3V 8-bit' found
> nand dump 0 /mnt/share/nfOcd0xa0000ddslc.img 0xa0000 0x4000

My jtag frequency was set to 1 MHz.

Is there anything which should be set to make faster slc mode?
