+=== Memory Limitation
+
+On SBCs with 512MB of memory, such as the GW5510, GW5100, GW5530, etc it is possible that a error appears related to memory.
+{{{
+[WARN]  VPU iram is less than needed, some parts don't use iram
+[ 6194.061104] mxc_vpu 2040000.vpu: Physical memory allocation error!
+[ 6194.067361] mxc_vpu 2040000.vpu: Physical memory allocation error!
+[ERR]   mem allocation failed!
+}}}
+
+This requires increasing the CMA memory in the bootloader:
+{{{
+setenv mem 'cma=96M'
+}}}
+
+The 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]
