Well, not TYPE=3DAP, but we'll integrate whatever is necessary into one firmware, I expect. It shouldn't be very hard given that AP mode really works with the TYPE=3DSTA firmware already, almost. > What does this mean: >=20 > eeprom : ORIGIN =3D 0x000000, LENGTH =3D 1024k >=20 >=20 > Does the device have whole 1M of eeprom? > What is there? The eeprom is mapped there, but I don't think it's 1M, it's just the max size of the mapping to the CPUs address space. > Also what is this: >=20 > sram : ORIGIN =3D 0x100000, LENGTH =3D 64k This is just memory. It's used for buffering frames and dma descriptors etc. internally. I want to change the code to do this with the linker script rather than manually assigning addresses in the source. But if you grep for this address you'll find how it's used. > Description says that pram is 32K, but: > =20 > pram : ORIGIN =3D 0x200000, LENGTH =3D 16k Yeah, we're not exactly sure about this yet, but using 32k definitely crashes the device. johannes --=-1DXZmgPadoca42y1QXNa Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJKK4vDAAoJEODzc/N7+Qma7UgQAKqMZgRxczqHMDNAV+NdeiU0 hQdbIaGVlLB2LiNbbfdFxEq/NUGUp8HIh8UXwlX+sWDBaFlD7z65yvxgzn/hO7L0 q6bc3MLihl7VMPlrnR3AUwEJzrGsrYyg2hCnGtdntyKJLrRWADxmREv99kFOx//F mC6qMC84viMIaV27hUvOPwBIBeX4+zItzXnp9jW5KccAG3RbB/yXPdhn+Pn7SYGy xvNryxllm6xcSoW3rlvbukgj1gQVOElvOOSqaK6eGCi6vIKTZE/JOmQ2iYLHm1TY 0nZLhppA1slYa3D6O0psNi4qGTorXIJehzFSZlokNmmm03XihK+dxCRaM2Tb2zpE U8SBIF3wT6lgHPeeaFzKoxsS3qXgaTheXwk5p4Uwuoj7RobhQhFbKZaGl2JctFcn BRCyx0kJPeHjK/6QXhF5EfWsHRdtPCkljHuUkQY6MzVcMRazNZ3FC+aMnmVbaV1D 0bFdOZpkuvUMDGYWavCRh6cveiNR2W3mzzJkCtAilc9ZC2uUM6ENJeLHOUi6rIJL Daj/pAcFj3ExCYivTaUNGzFO76GN7bZz1uLUlzjBq8+ImRqGYIV9crTOifFVwm6u 8z/98u7MHBgUyNpqN6eTsK3vuQ41IfquiVDbM7VcdbrKQ/suExgY7tGdI7bwyIkU T9vPyDcdbKy/O7AJMxjH =7/A/ -----END PGP SIGNATURE----- --=-1DXZmgPadoca42y1QXNa--
