Thank you Steve.
When I performed the erase it did not indicated any bad blocks. Is there a way to test for bad blocks? I don't think it is bad blocks however since both of our Davinci boards do this.

U-boot isn't smart enough to deal with bad blocks ... I have a board that has one in the middle of the kernel image. I moved it away from the bad block and changed the nboot address to match.

I just recently enabled some other options and it grew in size to 1.6 megs. Our nand flash layout is like this. 0x00000000-0x00018000 : "UBL image" 0x00018000-0x00044000 : "U-boot image" 0x00044000-0x00208000 : "Kernel image" 0x00208000-0x003ffc000 : "JFFS2" So we have more than enough space. I load the uImage into ram using tftpboot and then nand erase/nand write it out making sure I write all of it and erase enough space. However when I go to boot it I get the following: Loading from device 0: <NULL> at 0x2000000 (offset 0x44000) Image Name: Linux-2.6.10_mvl401-davinci_evm Image Type: ARM Linux Kernel Image (uncompressed) Data Size: 1646412 Bytes = 1.6 MB Load Address: 80008000 Entry Point: 80008000 ## Booting image at 80700000 ... Image Name: Linux-2.6.10_mvl401-davinci_evm Image Type: ARM Linux Kernel Image (uncompressed) Data Size: 1646412 Bytes = 1.6 MB Load Address: 80008000 Entry Point: 80008000 Verifying Checksum ... Bad Data CRC However, if I just bootm after I loaded it with tftpboot it works just fine. So there is some problem in the reading/writing to the NAND flash. Any thoughts?
