Re: [Firmware] BEFSR41 ver. 3

Thanks.
1. I know Google but I could not find anything useful information about my JTAG problem.
2. I tried to check the "ARP courtesy notification" of the router with Wireshark, but the router did not send anything. From another router I can received the expected message...
3. This kind of router has not serial port on the PCB (the serial pins of the CPU are not connected anywhere).

I'm not familiar enough with ARM/H-JTAG to know if you can create arbitrary reads. If so, can you go looking for valid data? That should get the FLASH location. Floating busses usually give themselves away (which may give clues to the DRAM, too).

Yes...
The KS8695 CPU (ARM922T core inside) has an MMU. The MMU translates virtual addresses into physical addresses. How does the CPU handle the memory in the BEFSR41 v3 router? I don't know. This is my problem...
The Google couldn't help me...
