SN 06:28 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: Simple Code/Doc for FPGA toggle of GPIO from DSP

Hi im trying to toggle a pin in the FPGA(busy/awake LED would do for now) from the DSP. Is there a doc(howto) describing the order of configuration/initialization and usage?.
Been looking at files from MDK_2014-01-13\sw\DSP\lib\core a... stefan nielsen

Thank Alex for your answer.
I think a problem was in incorrect PINMUX for UART-1.
My design works fine for UART-0 and UART-2.
Best regards,

Oleh,
Can you please share some more details about this issue if it is still occurring?
It looks to me like Uboot is interpreting the file as text and trying to execute the commands.
Presumably the DSP has not taken control of t... Alexander Block

AB 07:50 PM MitySOM-5CSX Altera Cyclone V FPGA Development: 100MHz Input clock (CLK2 - DDR3) Issue

A customer has the 100MHz DDR3 clock being fed into the module through Pins 117 and 119 on a custom carrier board and is using it to clock some ADC data. However after a little run-time it stops working as noted below: Alexander Block

You may have better luck with the latest MDK. MDK_2014-01-13 is the newest.

Which MDK version? Jonathan Cormier

CC 04:48 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: mtd->read() returned ECC error

I am using the mityomap-full.jffs2 supplied with the MDK. I "assumed" the filesize was the number of bytes transferred via tftp. Perhaps that is incorrect.

Chris,
Your flash commands seem reasonable though it is unusual that your file happens to already be exactly 0x800 byte aligned. So perhaps this would be something to investigate, doubtful though.
Its also possible you have some... Jonathan Cormier

I know this issue was addressed earlier in this forum. I followed the instructions given regarding the need to use the pre-fill memory and write in page sizes to keep the jffs2 filesystem correct. This, however does not seem to solve the... Chris Coonan
