- JC 08:56 AM MitySOM-5CSX Altera Cyclone V Software Development: RE: annoying problem with nfs root
- Note that the patch is for the 9021 but since we are seeing similar problems with the 9031 it seems safe to assume it affects both hardware.

- Hello,
I assume you mean the EMIFA clock (to FPGA) not the EMIF clock (used for the DDR).
I am sorry I missed this. I believe the EMIF clock gets initialized in the User Boot Loader (the UBL), a copy of which is included in the bo... - AB 01:50 PM MitySOM-335x (ARM Cortex-A8 Based Products) PCB Development: RE: Using RMII1 and JTAG

Please take a look at the [[Programming the FPGA]] wiki page for information about programming the FPGA.

I'am using CCS V5.3 and emulator XDS100V2.
I have developed SYS/BIOS ARM app. which use UPP to send/receive data to/from FGPA. Everything works fine(an interrupt is received when data has been sent/received to/from FP...

- I have two questions.
I have bought three modules with DevKit on Digikey.
But the Silicon revision is 1.0.
It's over a year in changing silicon, but you're selling old version up to now.
It's NOT GOOD.
First, MitySOM has I2C1_SD...

- MW 11:44 AM MityDSP-L138 (ARM9 Based Platforms) PCB Development: RE: uPP Interface
- I don't think that the UPP pins are pinmuxed (there is only one option if the UPP is used). See the MDK/sw/dsp/core/tcDspUpp.cpp for pinmux setting.
-Mike - OM 09:16 AM MityDSP-L138 (ARM9 Based Platforms) PCB Development: RE: uPP Interface
- Thanks Mike for reply.
The question will be, to what pins DSP connected pins FPGA? It needs to be known for purposes PINMUX.

- The UCF file in the board support package at MDK/fpga/vhdl/MityDSP_L138.ucf includes connection information between the UPP interface pins and the FPGA.
This is an excerpt: - Hi,
How to find out as are connected pins FPGA and DSP for the interface uPP?

- Hi,
Please check this "wiki page":https://support.criticallink.com/redmine/projects/arm9-platforms/wiki/CAD_Files and let me know if it does not provide what you need.

- Hi There,
Would it be possible to make available a 3D STP file of the MityDSP L138F
processor module for mechanical assembly design/modelling purposes?
Kind Regards,

- Hi John,
You are correct. We've pulled in this fix and it will get published in the next release for the MityDSP-L138 BSP.
Thanks for the bug report.
-Mike - FYI.
In tcDspFpgaGpio::ConfigurePin(unsigned int Bank, unsigned int Offset, etc.) and a few other fctns in DspFpgaGpio.cpp, there's a test for a valid value for the Bank arg and for the Offset arg, like:
