About am335x nand boot problems After that, the machine crashed. The initial solution was to re-burn the SPL and the problem was solved. Later it appeared again, and I didn't re-burn it, but suspected that the data in the flash was corrupted, but it shouldn't be, because the data is in the first block, and the first block should not be corrupted. Then I started with the SD card out of curiosity, read the content in the first block under uboot, and compared it with the burned image, and found that the two were exactly the same. Then I read the MLO in the nandflash into the memory first, then erased the first block, and re-wrote the data in the memory, and it was actually able to boot from the nandflash, it actually started! 〉〉〉Click for details Based on SDK7.0, how can I make AM335x run at 1G frequency?

After a month and a half of exploration, I finally migrated from SDK6.0 to SDK7.0, and now use the device-tree method.

U-boot initialized the frequency of 1G, but according to the following startup information, the kernel finally adopted the frequency of 600M. [ 0.000247] Calibrating delay loop... 663.55 BogoMIPS (lpj=3317760)〉〉〉Click for details

About the problem of using nfs to mount the file system! The hardware platform I use is AM335X starter kit, and the SDK version I use is version 04 (ti-processor-sdk-linux-am335x-evm-04.00.00.04-Linux-x86-Install.bin), the latest SDK on the official website. I have compiled uboot and kernel, and now I want to mount the file system through nfs.
