GSoC-2022 Hello-World Project for BeagleBone Black

[Prashanth S]

Hi All,

This is to send the Hello-World Project for BeagleBone Black BSP.

I am Prashanth S a working professional with experience of 3 years and 6
months. I wanted to be part of open source community especially
contributing RTOS, by taking GSoC-2022 as an
opportunity I like to contribute to BeagleBone Black BSP.

I have previously worked on beaglebone black, developing a learning tool
kit (Bare metal firmware with few supported peripherals CPSW, gpio,
interrupt).
GitHub - slpp95prashanth/Beaglebone-mBootloader at cpsw


Please find the attachment for the patch and screenshot for the hello world
project.

Regards
Prashanth S

[PATCH] shell: Avoid potential stack corruption

[Sebastian Huber]

The rtems_shell_init() passed the address of a stack variable
(exit_code) to rtems_shell_run().  If wait == false, then the stack
variable goes out of scope but may be accessed by the created shell
thread.

The rtems_shell_script() was affected by the same problem.

Close #4629.
