AD 11:31 AM MitySOM-5CSX Altera Cyclone V PCB Development: RE: Function of pin 46

Hi Malcolm,
Thank you for the question! This is an error in the table - the connection is +VIO_ENABLE_2V5 as noted in the schematic sheet. There are references to this pin's functionality in the Power Sequencing section under Electr... Adam Dziedzic

MH 10:14 AM MitySOM-5CSX Altera Cyclone V PCB Development: Function of pin 46

In the document MitySOM-5CSX-Carrier-Board-Design-Guide.pdf (March 31st 2015) on page 10, pin 46 of the SoM is described as GND.
On the schematic on page 20, pin 46 is connected to a signal labelled +VIO_ENABLE_2V5.
Is there a co... Malcolm Hartnell

AB 10:21 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: FPGA load fail

Bruce,
1) Can you please provide a complete boot log spanning from when the module is first powered on and including the CRC checks you are performing on the NAND memory?
2) Can you confirm how many months these units have been si... Alexander Block

Alex,
The main documentation for this is provided by TI: http://processors.wiki.ti.com/index.php/AM335x_ADC_Driver%27s_Guide

AP 05:39 PM MitySOM-335x (ARM Cortex-A8 Based Products) Software Development: Is ADC supported in the 3.2 Linux build?

I need a single ADC input for an ambient light sensor, and would like to use one of the pins not needed by the MitySom 335x dev kit touch screen, ain7.
What do I need to do under the current Linux to get a single reading from this p... alex peck

Alex/Jon/Tom,
Further to this problem, we have now had a few units where this problem can be seen. We have used the CRC check to verify that the data being read from NAND is indeed corrupted.
Interestingly, the two units where we ... Bruce Kenny
