fpga_load cannot read io mapped chameleon table from F401

[dpfeuffer]

The fpga_load tool should support to dump FPGA chameleon tables located at io mapped BAR. With the F401 board (which I want to send to Spain), I was not able to read out the chameleon table.

HW: F23P CPU, F401

I would assume to read out the chameleon table with one of these possibilities:

A)

Z100_PCIInit

I was able to dump the chameleon table with the help of the chameleon driver, so the chameleon table is present and can be read out with the chameleon library. Here is my MDIS configuration for F23P + F401 + Z51_DAC: f401.tar.gz

Chameleon table dumped with the chameleon BBIS:

Hi @dpfeuffer

I think I have fixed it, please, check the output of the fpga_load:

The IP Core number 7 is not detected because the modCode is not defined. Do you know which kind of IP Core it it?

I'm doing some tests and I think they will take this afternoon and tomorrow, but it looks good ;)

[dpfeuffer]

It looks good!

The IP Core number 7 is not detected because the modCode is not defined. Do you know which kind of IP Core it it?

Don't know if I understand your question correctly. IP core 7 is listed: 7 0x0032 16Z050_BIO 0 1 0 0 6 2 0x00000000 0xe001

Or do you mean scan_system.sh is not able to detect it? Z50 is a GPIO device: https://github.com/MEN-Mikro-Elektronik/13Z050-06

[mad-jrodriguez]

My bad Dieter,

I wanted to say, IP Core number 5, that appears with "?" or "not identified"

[dpfeuffer]

According to the F401 Spec, the IP core 5 is a debouncer:

This debouncer is reported with DevId 0xffff, because 0x3E DeviceID is unknown in chameleon.h.

The chameleon debugs should look like (see above for the full dump): [ 5269.792301] 05 ? 0x003e 0 0x00 0x08 0 0x0500 0x000000005a50d34d

But anyway, there is no MDIS driver for this debouncer. It is used to debounce the inputs of the 16Z050_BIO. The debouncer is configurable but it seems to me that it was never supported from a driver and only default values are used for debouncing. The modCode 0x3E is not official defined in our FPGA IP Core Overview document, so just let this IP core undefined.

[mad-jrodriguez]

Hi Dieter,

Ok, so I will leave such IP core as "undefined". Then, we have to update the scan_system script in order to avoid such kind of lines, otherwise the script will fail.

Thank you so much.

Hi @dpfeuffer

After the rework, the patches are ready. Now, the Chameleon table is dumped with correct values, even for the table version and revision
