- MW 07:23 PM Software Development: RE: Trouble with writing to UART2
- You need to use the TIOCRS485 ioctl on the serial port file descriptor with the serial_rs485 structure.
It involves writing a bit of code. You can't do it with any shell tools that I am aware of.
See the example code in the rs485_... - JY 07:08 PM Software Development: RE: Trouble with writing to UART2

- MW 03:06 PM Software Development: RE: Trouble with writing to UART2
- Hi Jeremy / Tim,
The link Tim pointed you to is for the MityARM-335x, not the MityARM-180x, though a similar patch exists for that as well for the RS-485 drivers.
Sorry for the confusion.
The patch you need is "here":http://su... - TI 03:00 PM Software Development: RE: Trouble with writing to UART2
- Jeremy
The RS485 board has an enable that must be managed. I believe you need a newer version of the driver to control it.
Support for the RS-485 board was added in commit 3e1a3878bbe545b7d4a2ab65023a9938b0d5984e

To confirm: are you looking for u-Boot code, or the User Boot Loader (UBL) code?
As Jonathan and Alex indicate, u-Boot is availble from GIT. The MDK should include a copy of the UBL project, which I believe was compil... - AB 05:00 PM Software Development: RE: U-Boot Source Code

The U-Boot source code is maintained in a GIT repository and not wholly contained in the MDK however a seed version of the GIT repository is included but you should update it to the latest.

- Have you checked the sw/ARM directory in the MDK?
-Jonathan - Does anyone know where I can find the U-Boot (UBL version 1.65:2.28) source code? Does the UBL source come bundled with the MDK? I am using MDK-2011-12-05.

- Hi Mike,
We are using your L138-FG-225-RC in combination with a propriatary base (=industrial IO) board --> MII is connected and used.
Stéphane - MW 10:07 AM Software Development: RE: Ethernet packet loss
- Are you using a custom board? Are you using the MII or the RMII port? If RMII, what device is sourcing the reference clock?

It’s not a u-Boot/Linux problem.
We are running SysBios on the ARM after leaving ROM code…
Best regards

- MW 07:01 AM Software Development: RE: Supply voltage for RVDD (internal ram supply)
- RVDD is connected to the CORE voltage.
So when you run at 456 MHz, the RVDD is bumped up to 1.3 volts as well.
The minimum core voltage that can be applied is 1.2 volts (even if you drop your OPP down to 200 MHz or below) because o... - Hello,
In the OMAP-L138 data sheet (sprs586d) chapter 2.8.27, I see that RVDD (internal ram supply) needs 1.2V respective 1.3V for 456MHz.

We are using the OMAP-L138 with SysBios on both ARM and DSP. In a test where we are sending nonsense data from the ARM to a PC, we reach a bandwidth from over 4MB/s with 8K UDP packets at 300MHz. When we now increase the CPU freq...
