[hpsdr] Metis, Mercury, Penelope Programming issues

[Walter Holmes]

More on this issue, that may be related.. 

It seems that there is some type of oscillation taking place, when I attempt
to start PowerSDR..(of course I have to select the  bypass firmware check to
get this far)

Whether I use the 2.6 Metis, or the Ozy board at 2.5, there is a squealing
sound being resonated from what sounds like the LPU area.

If I unplug the Ethernet cable from Metis, it stops. Back in, and it
restarts. Oddly, it does this when Ozy is used as well.

At least with Ozy, it shows the firmware for Mercury to be at 3.3 now. But
Penelope still at 0.0.

I am not sure if I am experiencing the same thing here myself, but here's
something strange I am seeing.

After not being able to update my existing Metis board for months, I decided
to buy a NEW one. (have not tried the JTAG cable yet)

It's currently on version 2.6 from TAPR.

The Metis bootloader seems to go through the motion to program it to 2.6,
completes the programming successfully.
But yet it never seems to change the version. It's still on 2.6

So I decided to update the Mercury and Penelope boards using the Bootloader.
It completed all the programming just fine, and shows on the screen that it
completed. 

But if I check them with the Interrogate function, the Hex code is still the
same, so not sure if it really changed the firmware version after all.

Since I wasn't completely sure, I installed my Ozy board, and used the
USB-Blaster, and flashed both Mercury and Penelope just fine. Again, no
errors, completed successfully.

However, here's where it seems VERY strange.

If I load PowerSDR 3.1.5,with Metis, it shows the Metis as v2.6,  but
Mercury and Penelope as 0.0, and of course it doesn't start PowerSDR.

If I use Ozy instead of Metis, I get the same message about Mercury and
Penelope as being 0.0.

Any ideas on what may not be correct ?

I removed the 2 jumpers for I2C and Bypass on Penelope, but could not find
them on Mercury, in case this was related the message attached here.. But no
difference.

Many thanks for any insight..

Hi Kjell,

Apologies, this should have been included in the user guide and release
notes.

The latest versions of Mercury, Penny and Metis FPGA code no longer use the
Atlas bus to transfer some low speed, or one time only, data.

We did this in order to free up some Atlas bus lines so we could increase
the Mercury sampling rate to 384ksps.

In which case the FPGA code versions in Mercury and Penny(lane) are
transferred  to Metis via the I2C bus.

This means that the I2C bypass jumpers on Mercury and Penny(lane) need to be
removed.

I'll update the relevant user guides shortly.

Hi All.

At last I found what the problems installing new firmware in Mercury and
specially in  Penny was. Programming Mercury went through after using the
USB-Blaster but doing the same with Penelope did not work. It seemed as
Penny blocked the communication over the Atlas Bus. Phil, VK6AP suggested
that I should check the I2C jumpers on the Penny card. They were both
installed and when removed, everything worked OK. On Mercury, the two
jumpers were not installed.

I did not know that some of the communication between Metis and
Mercury/Penny over the Atlas Bus was modified. In the description of the
Penelope card, the two jumpers should be installed. I can not remember
anything mentioned on the reflector about this?

I still have problems when trying to use HPSDRBootloader to program Mercury
and Penelope. After loading *_JTAG.rbf, the Erasing Flash reports timeout,
try again? But trying once more does not help.

73, Kjell
