Kernel doesn't come up - Hangs at Uncompressing Linux... done, booting the kernel on Zynq

Dear Xilinx community

 

Am seeing the below kernel hang issue which fails kernel to come up, could you please let me know how this issue can be resolved  I tried enablingthe following

CONFIG_DEBUG_LL=y
# CONFIG_DEBUG_VEXPRESS_UART0_DETECT is not set
# CONFIG_DEBUG_VEXPRESS_UART0_CA9 is not set
# CONFIG_DEBUG_VEXPRESS_UART0_RS1 is not set
# CONFIG_DEBUG_ZYNQ_UART0 is not set
CONFIG_DEBUG_ZYNQ_UART1=y
# CONFIG_DEBUG_ICEDCC is not set
# CONFIG_DEBUG_SEMIHOSTING is not set
# CONFIG_DEBUG_LL_UART_8250 is not set
# CONFIG_DEBUG_LL_UART_PL01X is not set
CONFIG_DEBUG_LL_INCLUDE="debug/zynq.S"
# CONFIG_DEBUG_UART_8250 is not set
CONFIG_DEBUG_UNCOMPRESS=y
CONFIG_UNCOMPRESS_INCLUDE="debug/uncompress.h"
CONFIG_EARLY_PRINTK=y

 

But still  dont see any reason why kernel is failing to come up logs as below

 

CONFIG_DEBUG_LL=y
# CONFIG_DEBUG_VEXPRESS_UART0_DETECT is not set
# CONFIG_DEBUG_VEXPRESS_UART0_CA9 is not set
# CONFIG_DEBUG_VEXPRESS_UART0_RS1 is not set
# CONFIG_DEBUG_ZYNQ_UART0 is not set
CONFIG_DEBUG_ZYNQ_UART1=y
# CONFIG_DEBUG_ICEDCC is not set
# CONFIG_DEBUG_SEMIHOSTING is not set
# CONFIG_DEBUG_LL_UART_8250 is not set
# CONFIG_DEBUG_LL_UART_PL01X is not set
CONFIG_DEBUG_LL_INCLUDE="debug/zynq.S"
# CONFIG_DEBUG_UART_8250 is not set
CONFIG_DEBUG_UNCOMPRESS=y
CONFIG_UNCOMPRESS_INCLUDE="debug/uncompress.h"
CONFIG_EARLY_PRINTK=y

 

Kindly do the needful as early as possible

Many Thanks in advance

Re: Kernel doesn't come up - Hangs at Uncompressing Linux... done, booting the kernel on Zynq

some more observation ie., Out of 10 times once the kernel boots and rest of the times it hangs at "uncompressing kernel"

Hi Srinivasan,

 

Please try with Default options without adding extra config options (Successful case) and then start adding  customised config options one after other , so that you can  identify the reason for Strange behaviour.

 

Thanks & regards
