     263=== Memory Limitation
     264
     265On SBCs with 512MB of memory, such as the GW5510, GW5100, GW5530, etc it is possible that a error appears related to memory.
     266{{{
     267[WARN]  VPU iram is less than needed, some parts don't use iram
     268[ 6194.061104] mxc_vpu 2040000.vpu: Physical memory allocation error!
     269[ 6194.067361] mxc_vpu 2040000.vpu: Physical memory allocation error!
     270[ERR]   mem allocation failed!
     271}}}
     272
     273This requires increasing the CMA memory in the bootloader:
     274{{{
     275setenv mem 'cma=96M'
     276}}}
     277
     278The example of 96M may or may not be enough, and should be experimented with. More information about CMA can be found here: [wiki:ventana/memory Ventana Memory]
