Hey guys

A very strange Error on my TCM-BF537 -Module has occured while testing other configurations of Host-Bus-Interface for my Epson S1d13513. The error occured while intitializing JFFS2-FileSystem.

The changes for the host bus Interface were that I connected WE1 to ABE1 for Upper Byte enable and WE0 to ABE0 for lower Byte enable. On Generic Interface these Pins are together in AWE Pin of the BF537. RD of the Epson I connected to ARE on Blackfin, and RD/WR of the Epson I connected to AWE on Blackfin. In generic Mode RD and RD/WR are to AWE connected. My proposal was that the so called 80 Type 1 Indirect - HostBusInterface for the Epson don't need the Sysclock of the Blackfin while Generic Mode needs the Sysclock.

The problem with the Sysclock is, that the CLKOUT Signal delivers 100 Mhz and the Epson only does 50 Mhz Busclock. During many testings with 100 Mhz CLKOUT the whole testing Environment crashed short after booting the devices. After I changed CLKOUT in U-Boot to 50 Mhz all worked well. But for other Applications I need the whole Sysclock on Blackfin.

That is the Reason why testing CLKOUT-less Configuration for Epson.

Now this Error occured during bootup the devices:

Michael,

Could you try to erase your nand flash with "flash_eraseall -j" and write image again?

Hi Yi,

I already deleted flash in U-Boot. An the same error occurs. But I can try your suggestion too.

Regards Michael

After deleting the whole flash in U-Boot it worked fine

Thanks Yi
