Title: TE0715 red led flashes 5 times
Post by: svedach on August 14, 2023, 09:21:33 AM
We made new base boards for TE0715, on power up the SOC starts but the red LED (D3, SC) blinks 5 times each. There is no description of this in the manual. Could this blinking mean some kind of problem? Or is the module functioning properly?

Hi,

in the old firmware this has the following meaning, see attachmet

Thanks, but I'm not sure which bank voltage we are talking about - is it the CPLD bank voltage or the FPGA bank voltage? And what's the boot mode? I would greatly appreciate a brief explanation.

Hi,
your module probably runs with the old cpld firmware which is not really documented well.
You could flash the new firmware for which the documentation is here:
https://wiki.trenz-electronic.de/display/PD/TE0715+CPLD#TE0715CPLD-LED(REDLEDD3)
Note that this it is a little tricky with TE0715 since the JTAG signals are routed a little different than on other 4x5 modules, cpld access works with carrier TE0703 and TE0705 which on their own need special firmware (https://wiki.trenz-electronic.de/display/PD/TE0715+CPLD+Firmware).

Blinking 5 times on your module is according to the new firmware the state: ON - Default state after power on
So it should be okay.

The bank voltage part is for the boundary scan - https://wiki.trenz-electronic.de/display/PD/TE0715+CPLD#TE0715CPLD-Boundaryscan

Bootmode -> After Power is turned on the DIP Switches determine the boot mode. It is possible to change the boot mode via linux console input - https://wiki.trenz-electronic.de/display/PD/TE0715+CPLD#TE0715CPLD-BootMode


best regards
Waldi
