HI Nikhil, We are using customized J6- DRA7xx board. We are trying to load the display DSS application ( bsp_examples_displayDss_m4vpss_release.xem4 image -vision-sdk ) via linux . We have attached the dts for the same. We are getting the below log messages. From the logs, only ipu2 image is loaded & up. But for the customized image ipu1, it is not loaded . What may be the problem ? how to debug ? calling omap_rproc_driver_init+0x0/0x24 [omap_remoteproc] @ 1116 [ 93.805765] omap-rproc 58820000.ipu: assigned reserved memory node ipu1_cma@9d000000 [ 93.818641] remoteproc0: 58820000.ipu is available [ 93.824547] remoteproc0: Note: remoteproc is still under development and considered experimental.
