As per my understanding “Logic loader” resides inside the Torpedo chip and X-loader and U-boot can reside either on NAND or MMC or split between NAND and MMC. The Torpedo, which is not working, does not boot the “Logic Loader” when there is No MMC plugged in. This is the observation on devkit environment. Nothing to do with OS bootup.
How can we erase Logic Loader? Is "nand erase.chip" erases "Logic Loader" too?
Thanks
