| 263 | === Memory Limitation |
| 264 | |
| 265 | On 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 | |
| 273 | This requires increasing the CMA memory in the bootloader: |
| 274 | {{{ |
| 275 | setenv mem 'cma=96M' |
| 276 | }}} |
| 277 | |
| 278 | 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] |
