7I97 + 7i74 SSereal problem

Hi,

I am using a 7I97 and a 7I74 to get multiple SSerial connektions.
I did load the "7i97_7i74D.bit" direktly from mesanet.com.
Loading the Bit file seamd to have woarked. but i can not use any otther than sserial_port_0.
when using sserial_port_1 the config dose not load and tels me that not more than one sserial is avaleble.
I have attached the Therminal output from me reading the mesacard config.
In the SSerial section it says:
Module: SSerial
There are 1 of SSerial in configuration

How can i change this on my card so it recognises that thear shuld be 8 chanels and not 1.

If thear is other information needed to find the source of this problem, tell me and i will do my best to provide the info.

The 7I97_7I74D firmware only has one sserial port (port_0).
This port has 8 channels, channel 0 on the 7I97
and channels 1..7 on the 7I74. (channel 0 is skipped
on the 7I74 to make the channel numbering match
the 7I74 documentation)

The reason for this is that 2 sserial ports will not fit
in a 7I97's FPGA (with the standard 7I97 I/O).

The 7I97T's 7I74 config does have 2 sserial ports and
9 total channels. (possible because of its larger FPGA).

Thanks for he fast reply,
I did try an 7i73 on wat i now guess is channel 0 of the 7i74.
this was not recognized so i tryed with the other ports in the HAL.
Wat i now think if i understand write is that if put on any other channel it shuld probably just be recognized.
I will try this tomorrow.
Againe thanks for the fast help.
 

Yes, if the channel in enabled in the hal file, it should be recognized.

You can see the 7I74 pinout a bit better with:

mesaflash --device 7i97 --addr [card_ip_addr] --dbname3 7i74

Hi,

I tried the other channels on the 7i74 today,
all of them work as they should.
Thanks again.
I noticed afterwards that in the thermal output I attached, IO 34 and 38 have no function, I assume that in different situations these would be RXData0 and TXData0.
So I should have noticed the fact that channel 0 is not available on the 7i74 in my case.
 

I/O 34 and 38 are  still available  as GPIO
(1 differential input and one differential output on the 7I74)
There might be room for some simple feature on those pins
(say PWM for output  or encoder 'A' pin for input)
