T1023 QorIQ-SDK-V1.7 Increasing ramdisk image higher than 32MB

[sangili]

Working in T1023 with QorIQ-SDK-V1.7.

When the "fsl-image-core-t1023rdb-xxxx" less than 32MB no issue while booting.

After development the image size got increased around 50MB, if we boot with this image we are getting following error while booting.

How to increase the ramdisk size in kernel/bootargs?

bootargs =/dev/ram rw console=ttyS0,115200,ramdisk_size=10240000

(below mentioned bootlog is for 40MB image size)

[Pavel]

Look at the following pages about increasing of the ramdosk_size:

https://www.denx.de/wiki/DULG/RamdiskGreaterThan4MBCausesProblems

and

https://www.denx.de/wiki/DULG/HowToIncreaseSizeOfRamdisk

Use the following the u-boot bootargs:

bootargs =/dev/ram rw console=ttyS0,115200,ramdisk_size= 41943040

Note: value of the ramdisk_size is in Kbytes.

Have a great day,
Pavel Chubakov
