I'm trying to use my EJTAG interface on a FBF 7050.
That interface worked well on a FBF ATA
These are the connections:
this is the interface layout
TRST -> 3V3 330 Ohm
cTRST -> 3v3 330 Ohm
TDI -> (pin 2)
TDO -> (pin 13)
TMS -> (pin 4)
TCK -> (pin 3)
I get this message:
There is a difference beteween ATA and 7050, 7050 have a coprocesso so
- EJTAG IMPCODE ....... : 00000000000000000000000000000000 (00000000)
- EJTAG Version ....... : 1 or 2.0
- EJTAG DMA Support ... : Yes
Issuing Processor / Peripheral Reset ... Done
Enabling Memory Writes ... Done
Halting Processor ... <Processor did NOT enter Debug Mode!> ... Done
Clearing Watchdog ... Skipped
Probing Flash at (Flash Window: 0x90000000) ...
*** Unknown or NO Flash Chip Detected ***
TDO became cTDO.
Maybe this the cause of problem?
