What's New in MDKARM Version 4.03a

• [RTX Problems solved]
  Important: if you are using RL-ARM ensure that you are also updating the RL-ARM library to V4.05
• [RTX Problems solved]
  Corrected: a problem in Round Robin task switching. This failed if a robin task was suspended by a higher priority task.
• [RTX Problems solved]
  Corrected: Stack checking did not work on system tick timer interrupt, only on preemptive task switches.
• [RTX Problems solved]
  Corrected: task switch monitoring in RT Agent did not work for Round Robin task switching.
• [RTX Problems solved]
  Corrected: incorrect event flag clearing in os_evt_wait_and() function if event flags were set separately. The following example shows the problem.

  __task void send_task (void) {
    os_evt_set (0x1, t_wait);
    os_evt_set (0x2, t_wait);
    os_evt_wait_or (0x1, 0xFFFF);
    os_evt_set (0x2, t_wait);
    ...
  }
  
  __task void wait_task (void) {
    os_evt_wait_and (0x3, 0xFFFF);
    os_evt_set (0x1, t_send);
    os_evt_wait_and (0x3, 0xFFFF);
    // Should never come here
  }
  

• [RTX Problems solved]
  Corrected: support for NXP LPC3180 device. RTX_Config.c configuration for RTX kernel was corrected. Added RTX_IRQ_Blinky example for Phytec LPC3180 evaluation board, it can be found in ..\ARM\Boards\Phytec\LPC3180 folder.
