Hi u-booters I'm at my wit's end. I really hope you can help.
I have tried updating the u-boot on a Davinci DM365 based board using various versions of u-boot, including the latest from the git repository. After setting CROSS_COMPILE and configuring with "make davinci_dm365evm_config", everything builds perfectly. I then install TI's UBL and u-boot.bin to a Micron NAND flash (MT29F16G08) using TI's sfh_DM36x.exe flashing utility. I set up the u-boot environment and boot the kernel, which I compiled from TI's DVSDK. Everything boots up fine, except for access to the /dev/mtd? devices. Also /proc/mtd exists but is empty of devices - it should show the partitions of the flash chip. Further investigation reveals that the davinci_nand driver simply returns from platform_driver_probe() with a ENODEV "No such device" error. What is the device that is missing, and why does it go missing when I boot with this u-boot? What makes some versions of u-boot activate this device in the kernel and others not? What is the mechanism by which u-boot can do such a thing? It seems to be something other than simple kernel command line parameters. How do I begin even looking for this problem? I hope you can help. Any pointers would be greatly appreciated.
