07:41 PM PCB Development: RE: Bootup Peculiarities: No lights come up on the module that lights up NCONFIG light.
On the second test module, both lights stay on until... Lucas Uecker
07:34 PM PCB Development: RE: Bootup Peculiarities: Hi Lucas,
It is sounding like the SOM might of gotten damaged. Does the green LED on the SOM turn on? This is the ... Daniel Vincelette
02:56 PM PCB Development: RE: Bootup Peculiarities: The Module that turned on our NCONFIG light did not boot on the dev board. I copied our NCONFIG LED from the dev boar... Lucas Uecker
02:48 PM PCB Development: RE: Bootup Peculiarities: Hi Lucas,
Did the SOM that was turning on the NCONFIG light on your baseboard boot fine in our Dev Kit?
What do... Daniel Vincelette

11:13 PM PCB Development: RE: Bootup Peculiarities: This is probing the HPS_POR_N: Lucas Uecker
09:13 PM PCB Development: RE: Bootup Peculiarities: Got together the dev kit:
-booted fine (both LEDs on the module came on, then one went off) with the microSD in an... Lucas Uecker
02:58 PM PCB Development: RE: Bootup Peculiarities: Here are the parts of the board in question and this version does look like a confused mess now that I'm looking at i... Lucas Uecker
02:45 PM PCB Development: RE: Bootup Peculiarities: We've used fancypants Sandisk "Industrial" ones, but also regular Sandisk branded ones. I'll put on the design review... Lucas Uecker

12:31 PM PCB Development: RE: Bootup Peculiarities: Hi Lucas,
In your boot log, I am seeing several error messages around the SD-MMC card (ext4-fs /dev/mmcblk0p* devi... Michael Williamson

08:58 PM PCB Development: RE: Bootup Peculiarities: Correction!
I held down the POR low a little longer and it booted...

07:56 PM PCB Development: RE: Bootup Peculiarities: No output from console on the module that has the NCONFIG light come on.
New module doesn't boot up, so no output fr... Lucas Uecker
05:14 PM PCB Development: RE: Bootup Peculiarities: Hi Lucas,
It looks like you do have the pull ups on CMD and D0. Can you post your console log of the SOM hanging d... Daniel Vincelette

02:25 PM PCB Development: RE: Bootup Peculiarities: Here's the relevant area on my schematic: Lucas Uecker
02:16 PM PCB Development: RE: Bootup Peculiarities: Hi Lucas,
Do you have the pull up resistors on the SD Card interface?
Have you looked at this support page on "... Michael Williamson

10:22 PM PCB Development: Bootup Peculiarities: Hello again.
I have built a handful of prototypes of our carrierboard and have had some boot up fine (I have it se... Lucas Uecker
