i.MX6 Solo board: System always hangs at "Uncompressing Linux... done, booting the kernel."

We are debugging i.MX6 Solo board with 512M DDR/JB422_100, and found system always hangs at:

Uncompressing Linux... done, booting the kernel.

 

the kernel command line is:

console=ttymxc0,115200 init=/init video=mxcfb0:dev=ldb,bpp=32 fbmem=10M fb0base=0x17b00000 vmalloc=200M androidboot.console=ttymxc0 androidboot.hardware=freescale

 

if we change vmalloc to 496M or higher, kernel can boot up, but system cannot work normally.

 

Anybody has any idea?

Please try to optimize memory layout, using the next threads :

“Memory Management on i.MX6 Android”

https://community.freescale.com/docs/DOC-93591

“iMX5 Android Gingerbread Memory Usage and Optimization”

https://community.freescale.com/docs/DOC-93334

Also it makes sense to test memory
