Tool/software: Linux
Hi all!
I have u-boot.bin working on on my board. At this moment I can load and start u-boot.bin from CCS or boot board from SPI NOR flash via u-boot-spi.gph image. But only in u-boot console. Linux don't start properly, and spinning in kernel code. Here description of problem:
All software components from Processor SDK. All of them was properly configured and build without errors as stated in appropriate manuals:
u-boot-spi.gph
skern-k2e.bin - compile with #define DEBUG
k2-fw-initrd.cpio.gz (not build - use from prebuilt images)
keystone-k2e-evm.dtb
zImage - compile with #define DEBUG in some files
Here the boot messages:
**** cut some output above ****

I was try to debug this issue, and found that processor is working in linux area code and not hung. I can connect to A15 Core0 in CCS via JTAG.
1) Can you look into debug messages from boot monitor, and tell about monitor install errors? May be installed address not valid? In ti wiki address noted as 0x0C140000 but in boot-monitor code install address is 0x0C1F0000.
2) Can you tell me, please about possible reasons of such behavior and how I can debug this issue? If you need any additional information I will provide it.
3) Can you look into u-boot environment settings and compare it with EVM settings? May be some addresses are not valid? Thank you.
4) On my board installed less memory than on evm. No NAND, SD. Please can you tell me, how I can fix this issue in dtb?
Thank you.
P.S. U-boot environment settings:
