- 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.
To what voltage source are these pins connected to? I just see 1.2V, 1.8V, 3.3V and the variable... - Hello,
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...

It seems that StarterWare is a feasible option.
If I understand correctly, StarterWare will create an image that will be loaded to the NOR flash memory and replace (or not?) the linux kernel. U-Boot w... - MW 06:43 AM Software Development: RE: Linux boot time on the MityArm1808F

We have not tried to much to get the boot times down to the levels that you are requiring.

- Based on Jonathan's comment, it appears that ftp is not supported on this platform. Guess it'll have to be sftp.
Thanks for the help.

2 - You don't have a nameserver configured.

Sorry for the delay. Can you please post the part number for your board? On some of our older boards there was a problem with the USB_ID pin on the OTG connector. Let's make sure that's not the issue.

You can configure ssh keys to allow transfers without having to type a password in, if you need it.

Just hit a key and break and load the code manually?
If you want the FPGA to be loaded, then we often make a separate script for loading the fpga, e.g:
