04:38 PM MitySBC-Agilex5 FPGA Development: RE: MitySBC A5E: Thank you for the information. I am guessing the pre-installed FPGA does not enable FMC_EN_3V3.
I will start with o... Sung Lim
04:24 PM MitySBC-Agilex5 FPGA Development: RE: MitySBC A5E: Hi Sung,
From the datasheet (page 14):
"All power to the FMC connector is gated by FMC_EN_3V3 which is tied to ... Michael Williamson
03:06 PM MitySBC-Agilex5 FPGA Development: MitySBC A5E: Two questions:
1. On the prototype board, FMC +12V and +3.3V do not appear to be driven. Is there a strapping optio... Sung Lim

06:44 PM MitySOM-AM62, MitySOM-AM62A, & MitySOM-AM62P PCB Development: RE: SOM_62P Reset on LED_RTN: Wondering if you could add a LPF filter (cap + R) across your FET to make the switch less aggressive. Kind of hacky,... Michael Williamson
06:28 PM MitySOM-AM62, MitySOM-AM62A, & MitySOM-AM62P PCB Development: RE: SOM_62P Reset on LED_RTN: That explanations seems probable, if I have any free time coming up I'll play around with the circuit on our side to ... Adrian De Vico
06:15 PM MitySOM-AM62, MitySOM-AM62A, & MitySOM-AM62P PCB Development: RE: SOM_62P Reset on LED_RTN: Hi Adrian,
Haven't seen this before.
This is a snippet from the SOM schematic related to the Power Good LED a... Michael Williamson
05:45 PM MitySOM-AM62, MitySOM-AM62A, & MitySOM-AM62P PCB Development: SOM_62P Reset on LED_RTN: We have a series of switchable LEDs on board for basic debugging of various on-board supplies, and for completeness I... Adrian De Vico

We are planning to purchase the heat spreader (part number 94-900813-3) for the MitySOM-AM57F SO... Bhima Shankar
01:13 AM MitySOM-5CSX Altera Cyclone V FPGA Development: RE: Building the MitySOM-5CSX: In the above, I don't know where the strike-thru lines came from. John Iannuzzi
01:12 AM MitySOM-5CSX Altera Cyclone V FPGA Development: RE: Building the MitySOM-5CSX: Additionally, in comparing the provided sd card with the built one, I found that the directory, *scripts_auto* , doe... John Iannuzzi

02:47 AM MitySOM-5CSX Altera Cyclone V FPGA Development: RE: Building the MitySOM-5CSX: This past weekend I was experimenting with the provided sd card and the examples. Specifically the LED example to li... John Iannuzzi

12:37 AM MitySOM-5CSX Altera Cyclone V FPGA Development: RE: Building the MitySOM-5CSX: Hi Seth,
For the 1st bullet point above I followed your instructions using the *command line* and it worked. Great!... John Iannuzzi

07:51 PM MitySOM-5CSX Altera Cyclone V FPGA Development: RE: Building the MitySOM-5CSX: Hi John,
Thank you for the additional details. *dd* typically will take a moment to return the prompt, it does on ... Seth Graber
07:20 PM MitySOM-5CSX Altera Cyclone V FPGA Development: RE: Building the MitySOM-5CSX: Hi Seth,
All I did was extract the image and dd it right to the sd card. I will read in more detail your comments w... John Iannuzzi
03:09 PM MitySOM-5CSX Altera Cyclone V FPGA Development: RE: Building the MitySOM-5CSX: Hi John,
Thank you for providing the 3 boot outputs. I've gone ahead and taken a look and I'll make some comments ... Seth Graber
03:19 AM MitySOM-5CSX Altera Cyclone V FPGA Development: RE: Building the MitySOM-5CSX: Ok, so I downloaded the sd card from the website as instructed, and loaded it onto a fresh card.
I now have 3 _dif... John Iannuzzi

01:46 PM MitySOM-5CSX Altera Cyclone V FPGA Development: RE: Building the MitySOM-5CSX: John,
Taking a look at your output it appears like you successfully recompiled the SPL and UBOOT. The differences ... Mike Fiorenza
02:19 AM MitySOM-5CSX Altera Cyclone V FPGA Development: RE: Building the MitySOM-5CSX: Hi, so I was able to make uboot and an sd card image. I took the image and loaded it to a blank sd card and powered ... John Iannuzzi

06:55 AM MitySOM-5CSX Altera Cyclone V FPGA Development: RE: MitySOM-5CSX (5CSX-H6-42A-RI) stops at “Deasserting all peripheral resets” — request for guidance: Hi Mike,
Thanks for your quick reply.
Here’s what I’ve tried and what I’m seeing:
