raspberry pi: Problems with the dynamic work area

Hello, the patch https://git.rtems.org/rtems/commit/?id=a4d7e4cee77d16b0e34ef543f0804e7eb2954137 introduced some problems. It tries to adapt the work area based on the size of the available memory. In theory this is a good idea but the implementation doesn't work. The line uint32_t mem =

Raspberrypi3: Mini UART driver

The rpi1 and rpi2 use the PL011 UART, whereas, with RPI's equipped with wireless/Bluetooth module, the PL011 is connected to the Bluetooth module, and the mini UART is used as the primary UART. https://www.raspberrypi.org/app/uploads/2012/02/BCM2835-ARM-Peripherals.pdf But from the above doc (PAGE

Re: raspberry BSP: Maybe there is a bug in the linker file?

Hello Niteesh, thanks for the detailed information. I agree that this is a completely different hardware module and will need a different driver. The data sheet (by the way: one of the worst I've ever seen) tells that the Mini UART has "16550 like registers" that are "as far as possible [...] lik
