mz: You used the term "transferring the kernel" which set off a discussion. I have been programming on the BBB for several years, and have not had to touch the kernel, which is part of the OS image. Some people want to learn kernel programming. OK . In my case, for any application development I have done, stock kernels have worked fine, and you can load new application code into a running BBB many ways. I use an SSH transfer over Ethernet from my host computer. For standalone applications, you don't have to stop or reboot the BBB. The only requirement is that you stop any application or executable of the same name, so that Linux lets you overwrite it.
You will get as many opinions on tool chains as there programmers. I generally do application/executable development in "C". Use Eclipse as the IDE, GCC cross compiler, running on a Linux desktop, or Linux on a VM running on a PC. Eclipse has an option to automatically transfer an executable (SSH over Ethernet) into the target BBB as soon as it compiles. Derek Molloy's book and his website videos tell you how to configure all of this. --- Graham --- On Thursday, September 29, 2016 at 7:13:30 PM UTC-5, William Hermans wrote: > > Not only that but if you make a mistake, and render the eMMC unbootable. > How would you fix it without an sdcard ?
