Hello, I have a first success in porting LinuxTV to my STB containing the Fujitsu MB86H2x DVB Processor. At the moment a uClinux kernel 2.4.29 is running and I have integrated the dvb kernel sources into the kernel (not as modules because the uClinux port does not support). But here is the problem: When attaching the TDA10046 frontend device the DSP firmware cannot be loaded from file because the root filesystem is still not accessible when the DVB modules are initialized. Is there another version of the tda1004x module which has the DSP firmware "integrated"? Hopefully, Thomas ---- Here is the boot log: Linux version 2.4.29-uc0 (thomas@debian) (gcc-Version 3.4.4 cod ito 20050725 [ derived from FSF snapshot on 26th Jan 2005 ]) #40 Mo Nov 7 22:25: 27 CET 2005 Detected Processor Number :1, Version :8 (ARCtangent A4 processor family) Linux configured to run at CPU speed : 154.00 Mhz Detected I-cache : Type=Direct Mapped, Line length=32, Cache RAM Size=4096 (enabled) Detected D-cache : Type=Direct Mapped-2 Stage, Line length=32, Cache RAM Size=2048 (enabled) initrd_start = ec000 , inird_end = 109c00 On node 0 totalpages: 512 zone(0): 0 pages. zone(1): 512 pages. zone(2): 0 pages.
