Aside from the previous change to increase the size of the ramdisk partition in NAND to 30MB, you can increase the amount of reserved kernel memory for it in u-boot by:
setenv ramdisksize 75000 which increases the memory for the ramdisk from ~64MB to ~75MB. Again, "savenv" after updating ramdisksize will save the change for the next reboot... -- Peter Barada [email protected]
