- Mike,
FYI It was the bias resistor. There was a type in the BOM and a 49.9K was installed instead of a 4.99K. ...

Just to be sure can you tell me how you pinned out the PCB footprint. Does it match this picture looking fr... - 03:57 PM FPGA Development: RE: TLK100 Ethernet
Mike,
After talking this out with our software guy we are convinced its as your said,one of two things. The con...- 03:49 PM FPGA Development: RE: TLK100 Ethernet
- Power up the unit in your board. Stop at u_boot and type:...
- 02:05 PM FPGA Development: RE: TLK100 Ethernet
- The JTAG R's and connector are not installed.
I have the ethernet connected to my home switch.
I set the ... - 01:55 PM FPGA Development: RE: TLK100 Ethernet
- Hi John,
It looks like the OMAP MII interface is not making it to your network. The 169.254.X.X network means tha... - 01:12 PM FPGA Development: RE: TLK100 Ethernet

- I didn't write them down I just typed them when he told me to. This was in u-boot. Once I typed them in I could pi...
- 07:31 AM FPGA Development: RE: TLK100 Ethernet
- What were the software commands? If they involved setting the peripheral configuration in u-Boot, then they only nee...

- 08:34 PM FPGA Development: RE: TLK100 Ethernet
- hey would it be possible that we talk on the phone?
858-254-0008
- 08:20 PM FPGA Development: RE: TLK100 Ethernet
- That message is OK. You can set up ethernet to use MII or RMII (but not both, and you're using MII).
It looks lik... - 08:06 PM FPGA Development: RE: TLK100 Ethernet
- I saw this among the test
EMAC: MII PHY configured, RMII PHY will not be functional
I attached the whole text - 07:50 PM FPGA Development: RE: TLK100 Ethernet
- Can you dump out the text from the boot sequence? Does the u-Boot locate the PHY (via the MDIO scan)?
-Mike
- 07:42 PM FPGA Development: RE: TLK100 Ethernet
- OK I made all the changes and it still does not work. I now think there are only two difference between out circuits...
- How do you recommend we handle shutdown of our embedded device in order to ensure the consistency of the Linux file s...
- 12:02 PM Software Development: RE: LCD/Display questions
- We were able to get the LCD going with no problem, BTW. We'll be using it for our demo next week.
Thanks for the h...

- 04:35 PM FPGA Development: RE: TLK100 Ethernet
- yes. you should add a pull-up.
- 04:16 PM FPGA Development: RE: TLK100 Ethernet
- Mike,
The green on the component means I used a different value cap or resistor. C216 is there but I used a 1uF c... - 03:46 PM FPGA Development: RE: TLK100 Ethernet
- Hi John,
I think you need to tie the RESET line on the phy to the MII_RESET_N signal. The SYS_RESET_N does not ge... - 03:23 PM FPGA Development: RE: TLK100 Ethernet
- More information for you.
Attached is a comparison between the Critical link schematics and ours schematics. View... - I know this is outside of your support area but I thought I would ask this in case you might have an idea of what to ...

- 02:28 PM Software Development: RE: LCD/Display questions
- You'll need a different FPGA image. You also need to load an additional module (for the touchscreen controller on th...
- 02:26 PM Software Development: RE: LCD/Display questions
- Yup. That did it.
For some reason, I had copied the instructions for the Rev. C board instead of the ones above.
... - 02:05 PM Software Development: RE: LCD/Display questions
- Ah. OK. You punched in the i2c commands for the Rev C board. You have 0x3f programmed into position 0x08.
Please... - 01:53 PM Software Development: RE: LCD/Display questions
- I added a simple test pattern generator to the wiki [[LCD_configuration]]. It draws a white box around the border of ...

- 04:16 PM Software Development: RE: LCD/Display questions
- Definitely not a Rev C board, so it must be a B (I think we have an A here as well, but this isn't it).
Yes, actua... - 03:22 PM Software Development: RE: LCD/Display questions
- Can you please confirm the revision of your board (B, or C)?
Before you write to the /dev/fb0 device, do you see a... - 03:13 PM Software Development: RE: LCD/Display questions
- Got it working. A few oddities, but I'm now able to at least talk to the frame buffer.
The screen is all blue and ... - 10:07 AM Software Development: RE: LCD/Display questions
- William
If you are seeing blue vertical stripes (every other pixel) then the frame buffer is working..
try the foll...

- 06:32 PM Software Development: RE: LCD/Display questions
- It's off the [[Das_U-Boot_Port]] page from the start page. I'll look at making another entry.
- 06:06 PM Software Development: RE: LCD/Display questions
- Could you put the link to that wiki page into the wiki start page please.
- 05:52 PM Software Development: RE: LCD/Display questions
- The [[LCD configuration]] wiki page has been started that will cover the information you need. It's a work in progre...

- 04:12 PM FPGA Development: RE: Critical link bit file
- Actually John,
you shouldn't need to reprogram the NAND/root filesystem. Only the kernel. The NAND should still ... - 04:10 PM FPGA Development: RE: Critical link bit file
- Right. The procedure you just ran only reloads the bootloader images.
You will also need to reload the kernel i... - 04:03 PM FPGA Development: RE: Critical link bit file

- It was my fault not yours so no big deal. If you can post what it takes to re-flash the boot code. If this doesn't...
- 07:54 AM FPGA Development: RE: Critical link bit file
- Hi John,
Well, the bad news is that I think you whacked the bootloading code on the SPI FLASH.

The API will be ALSA.
My best guess would be something mid-October. We'll try to bump it up on the p...
