10:18 AM MityDSP-L138 (ARM9 Based Platforms) FPGA Development: RE: FPGA serial programming interface
I discussed this with one of our engineers here and it may be possible however they is likely a bit of work required ... Alexander Block
08:32 AM MityDSP-L138 (ARM9 Based Platforms) FPGA Development: RE: FPGA serial programming interface
SB,
I apologize.
The M0 and M1 FPGA pins are tied to resistors on the module to GND (M0) and 3.3V (M1) forcing...

05:04 PM MityDSP-L138 (ARM9 Based Platforms) FPGA Development: RE: FPGA serial programming interface
I understand that. However, I would like to configure the FPGA in serial slave mode. stephan berner
05:01 PM MityDSP-L138 (ARM9 Based Platforms) FPGA Development: RE: FPGA serial programming interface
SB,
The FPGA is configured using 8 bit parallel slave select mode via the EMIFA bus connection to the Omap L138 pr...

06:44 PM MitySOM-5CSX Altera Cyclone V Software Development: RE: Very high TX packet loss on gigabit Ethernet
Hi Mike,
I don't think those pins are associated with an IO bank. In the pin planner the default setting for those ...

06:24 PM MitySOM-5CSX Altera Cyclone V Software Development: RE: Very high TX packet loss on gigabit Ethernet
Hi Chris,
Can you expand a bit? Do you mean the IO bank voltage settings were not correct?

05:58 PM MitySOM-5CSX Altera Cyclone V Software Development: RE: Very high TX packet loss on gigabit Ethernet
Hi Mike,
I/O parameters turned out to be the problem. They were set to their default values (higher than they shoul...

04:47 PM MitySOM-335x (ARM Cortex-A8 Based Products) Software Development: RE: MAX3100 (SPI to UART bridge) driver not working
Bindu,
You can look at how the other baseboard_spi0_slave_info have the irq filled in. Its possible that simply n...

09:50 AM MitySOM-335x (ARM Cortex-A8 Based Products) Software Development: RE: MAX3100 (SPI to UART bridge) driver not working
The init driver gets called when the driver is added to the kernel. If its built in then this happens early on, if i... Jonathan Cormier

10:48 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: MDK_2012-08-10 default configuration
There also may be a small time penalty in having the kernel search for the phy. But this would need to be quantified ... Jonathan Cormier
10:46 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: MDK_2012-08-10 default configuration
I believe the phy address was set in an earlier version of the kernel and it was carried forward. There is also the ... Jonathan Cormier
09:52 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: MDK_2012-08-10 default configuration
Thanks Mike for answer.
I did not look at section 2.2 of TLK100PHP datasheet. It is my fault.
I read section "3...

09:18 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: MDK_2012-08-10 default configuration
Hi François,
In the datasheet for the TLK100PHP, Section 2.2 shows that the PHYAD0 pin has an internal pull-up, wh...

07:33 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: MDK_2012-08-10 default configuration
I look at U-boot code and it doesn't explain what we are seeing.
When resetting the PHY device, only GPIO5[15] is ...

04:43 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: MDK_2012-08-10 default configuration
François,
I too was confused about this but was unable to determine why the phy id becomes 0x03.
I checked th...

04:21 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: MDK_2012-08-10 default configuration
Mike,
My reply is out of date but it is about that topic: PHY address configuration.
You said that PHY address ...

03:59 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Write to SharedMem from DSP and read it from ARM
Pretty sure you have to flush the DSP cache after changing values. Jonathan Cormier
03:48 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Write to SharedMem from DSP and read it from ARM
Hi,
I am trying to get the shared memory working as well (by writing from DSP side and reading back from ARM side)...

Thanks Jonathan, that's exactly what I was after. Mostafa Afgani
11:41 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Alter Ethernet MAC
You might also try this technique, though I am not sure if the current version of the 3.2 kernel has this command lin... Michael Williamson

Mostafa,
We store the mac address on a eeprom on the SoM. The settings stored on this can be accessed using the f...

11:01 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: Alter Ethernet MAC
Hi, is it possible to alter the 'burned-in' MAC address of an L138F? I know that I can change it using 'ifconfig eth0... Mostafa Afgani
