Tool/software:
Hi Ti expert
SDK: 10.01
Board: J784S4_EVM
I used dfu to flash ospi, and booted from ospi, and used initramfs.
After I finished the first stage of flashing and entered uboot, I used the following command to layout dfu_alt_info_ospi:env default -f -a
setenv dfu_alt_info_ospi "tiboot3.bin raw 0x0 0x080000; tispl.bin raw 0x080000 0x200000; u-boot.img raw 0x280000 0x400000; u-boot-env raw 0x680000 0x020000; Image raw 0x6c0000 0x1300000; K3-J784s4-dtb raw 0x19c0000 0x020000; rootfs raw 0x19e0000 0x2620000"
setenv dfu_alt_info ${dfu_alt_info_ospi}
dfu 0 sf 0:0
When I back to HOST:
Now I use dfu to flash all flash.
And then switch boot mode to ospi and enter uboot:
Then I use the following command to set the startup parameters：setenv bootargs "console=ttyS2,115200n8 earlycon=ns16550a,mmio32,0x02880000 vm.overcommit_ratio=5 vm.overcommit_memory=2 root=/dev/ram0 rootfstype=ramfs initrd=0x84000000 init=/init"
setenv bootcmd "setenv autoload no; sf probe; sf read 0x82000000 0x6c0000 0x1300000; sf read 0x81200000 0x19c0000 0x20000; sf read 0x84000000 0x19e0000 0x800000; booti 0x82000000 0x84000000:0x800000 0x81200000"
boot
But when booting , booti can not found dtb...:
When I flashed all the firmware in the second stage, including dtb, Image, roofs.cpio, there were no errors and all were downloaded successfully.
When I checked the loading address of dtb, I found that it was empty
How to solve this problem?
