Re: Modify Mac Address

Just to update this topic, we've committed a change in Ultibo Core 2.0.723 which allows specifying the Mac address in the cmdline.txt file in much the same way you can specify a static IP or other configuration options. So now you can add something like this: NETWORK0_HARDWARE_ADDRESS=B827EB123456 t...

Re: Bit-banged 8-port RS-232 communication library

Course, then I really wouldn't need Ultibo, as Raspbian could handle all the serial ports. Unless you are also interested in reduced complexity and increased reliability. We think that a single application immutable binary image like Ultibo will produce a more reliable (and more maintainable) resul...

Re: Raspberry Pi 4 and Ultibo

I am building a new system and it is failing. see https://gist.github.com/develone/f0b9131774bede3e9894bff5047c74c0 where it fails Hi develone, Yes that looks exactly like the error you get when there is not enough swap file available. If anyone has a 2GB or 4GB Pi 4 it would be interesting to know...

Re: Bit-banged 8-port RS-232 communication library

All that to say...RS-232 was designed as a long-range communications protocol, and at least in my case, it's what I need to use. Fair enough, just asking the question to be sure you have considered all options. Can you share a link to the Pi Zero's register map? The official register documentation ...

Re: Bit-banged 8-port RS-232 communication library

Hi ZeroHobby, welcome to Ultibo! SO: I am wondering if an 8-port (bit-banged) 9600baud RS-232 driver could successfully be written in Ultibo for the Raspberry Pi Zero? (Anything can be written, the question is whether it'll actually work :twisted: ) While you are correct that anything can be written...

Re: Modify Mac Address

That works if you always want to use the same hard coded Mac address but it is also possible to set the Mac address in code by shutting down the interface, changing the Mac and then enabling the interface again, we're just putting together a simple example that shows how to do that which we'll post...

Re: Modify Mac Address

I want change the Mac address that the LAN9512/9514 uses when running under Ultibo, let me know how to change The first option is to use an InitUnit, which we have shown in a number of other examples, to set the value of SMSC95XX_MAC_ADDRESS during startup to the Mac address you want to use. The In...

Re: There is a RPi4 on the wild

There is so much graphics capability that it would be hard to do it justice anyway. That's not really what we meant by major change, the Pi 4 doesn't contain any revolutionary graphics capabilities (most PC graphics cards could walk all over it), the change is that the driver for the 3D graphics (O...

Re: There is a RPi4 on the wild

At the risk of sounding obnoxious to progress lovers, I'd prefer having Ultibo handle the raspi radio module first, rather than having it compatible with the new Raspberry 4. We completely understand the sentiment of this, having the Pi 4 appear more than 6 months ahead of what was expected has mea...
