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 dumped 16384 bytes in 481.742981s (0.033 kb/s) > My jtag frequency was set to 1 MHz. Is there anything which should be set to make faster slc mode?
