I think EEPROM in general is working. Do you have specific EEPROM to try?

for eeprom, i see SPI and I2C protocol support, but not MICROWIRE.

here is specific eeprom:

MICROWIRE protocol is subset of SPI, but not the same protocol (data latch is different).

I see. I do not think USB JTAG NT can support it. The slowest clock is 6M. But I will keep this in mind.

Default Restoring DCT3416 back to life

Welcome to all past/present Cable Box Testers ! I pulled one of my fave boxes out of closet, a first generation HDMI w/ 160 GB Hard Drive and found that it had gone into Hunt mode and lost its identity. And, now that a new Firmware has been introduced, it lost its NVRAM and, this is where the Testing begins. This unit uses the EJTAG64 platform and the DCT6412 dll which is identical. After attaching a 10 pin Header onto the board, even an old head like me has been unable to start Testing. All I need do is to copy a valid 3416 NVRAM back on board and, I've found this to be exceptionally difficult to accomplish, just like it was several years ago. It will not Detect the Intel Flash on board, supplying values like 0000000 or FFFFFFF. And, DEBUG ON appears but, setting the NVRAM moves forward only one block on the progress scale and runs no faster than 20 Kbs and quickly hangs due to Watchdog. This box was always difficult back in the day and, remains so today. I DO want to revive this unit and, use it to record stuff. The Watchdog shouldn't matter with a 256 Kb NVRAM. I'm stuck and a bit angry. Are there any creative ideas I can use to speed the Testing process ? Thanx and, a goodday to one and all.
