Re: Demo Image has Specific uSD requirements

Just to update, we tried some initial tests to see if we could reproduce this. We no longer have a 4GB SD card so we tested formatting an 8GB with no partitions and everything works fine, then we tested creating a single 4GB FAT16 partition (the maximum possible with FAT16) and again everything work...

Re: Demo Image has Specific uSD requirements

Hi mvandere, Welcome to Ultibo. 1. The uSD must be partitioned. 2. The Partition cannot be greater than 2GB. Thanks for the information, we will test both of those and either fix anything we need to or (if the problem is in the Pi firmware) add a note to the demo to warn others about it. Out of inte...

Re: RaspiCam for Computer Vision

It is blocked in the "fopen" line 554 of function _RaspiCam_createImageWithEncoder (Code C, file RaspiCamWrapper.c). From there it does not continue, only continues when I remove the SD and surely force to leave the fopen. What could be the problem? I have tested your code and it works ev...

Re: New Ultibo FPC and Lazarus Linux installation script (Testers wanted)

On raspbian stretch, using lazbuild, I'm unable to figure out how to suppress these messages. I do want to see warnings/notes/hints referring to source code The ones that refer to (lazarus) can be removed by passing -q or --quiet to lazbuild. The others seem to come from FPC itself, adding -vh- (to...

Re: RaspiCam for Computer Vision

I have been reviewing the fp-image documentation, is there any way to create an fp-image using an RGB array and the size of the image (width and height)? Probably the simplest option would be to create a new TFPArrayImage class that descends from TFPCustomImage to allow you to pass an RGB array (pl...

Re: Regarding baremetal programming

I see you posted a very similar question on the Raspberry Pi forum so I won't try to answer your questions in any more detail because that might make things more confusing. What I will say is this, because you seem to be focusing a lot on the mailbox code used to hold the secondary cores in a loop w...

Re: Threads and Processors

Then I started the 1st DedicatedCPU. Both WebSevers are running an CPU 3 is at 100%. Not seeing Counter of 2nd DedicatedCPU ever start increasing. I don't see anywhere that you are setting the function of pin 21, it will most likely be an input or an output on boot so either the first or second ded...

Re: Resources for Multithreading

Could some one please put the resources which can give a person sufficient knowledge on how to implement threading from scratch (even scheduler too) . Threading and scheduling is a very big subject and is far too much to cover in detail here. The best place I can suggest is to start with the releva...

Re: Threads and Processors

Where do I find information about ... For reading a GPIO pin. The GPIOPinOn() and GPIOPinOff() procedures shown earlier in this thread are modified from the GPIO functions in the BCM2709 unit which are all created using information from Section 6 of the BCM2835 ARM Peripherals document. To complete...

Re: Building Lazarus in Debian/Raspbian

I did not see the Tools/Build RTL in the Lazarus running on RaspBian. The Build RTL tool has not been ported to Linux yet, that will happen at some point in the future. Are there any problems rebuilding the RTL in this method? No, it is quite okay to rebuild the RTL this way. This is almost the sam...
