Hi,
We are working on a custom DM8148 board that has asymmetric EMIF configuration -- EMIF0 has 512 MB and EMIF1 is not installed. We have modified the u-Boot code to configured the LISA registers to provide duplicate mappings of the space between 0x80000000 and 0xA0000000 according to the defines below. We've tested the memory in several ways and there doesn't seem to be an issue with the hardware.
#define PG2_1_DMM_LISA_MAP__0 0x80500100
#define PG2_1_DMM_LISA_MAP__1 0xA0500100
#define PG2_1_DMM_LISA_MAP__2 0x80500100
#define PG2_1_DMM_LISA_MAP__3 0xA0500100
We are able to boot the DVRRDK kernel up and load several of the modules, etc. But when we try to launch the DSP firmware, the DSP is not able to connect to the HOST. The m3vpss and m3video firmware seems to come up fine. A log of the init and load scripts is shown below. For what ever reason, the DSP can't connect to the HOST and vice-versa and the IPC_attach times out with a syslink error. Any ideas what the problem might be? We are migrating from the EZSDK, which is exhibiting what appears to be the exact same problem. Is the memory configuration creating a problem for the DSP core?
