What's New in RL-ARM Version 3.03

• [Real-Time Library]
  Added support for Atmel AT91SAM7X devices. Added the RTX_CONFIG.C RTX Kernel configuration file and the AT91_EMAC.C embedded EMAC Ethernet controller driver. Preconfigured examples for the AT91SAM7X-EK Atmel Evaluation Board are located in the \KEIL\ARM\RV30\RTL\BOARDS\ATMEL\ folder.
• [RTX Kernel]
  Added mutex task priority inversion/inheritance. When a medium-priority task preempts a lower-priority task using a shared resource (a mutex) on which a higher-priority task is pending, the priority of lower-priority task is temporary raised to the priority level of a higher-priority task. As soon as the lower-priority task releases the mutex, its priority level is restored to its original value.
• [RTX Kernel]
  Corrected a problem in RTX_CONFIG.C for all Atmel devices. The interrupt acknowledge sequence was incorrect and could cause system dead-locks when additional IRQ interrupts were enabled. If isr_xxx_ functions were called from the interrupt handler, the interrupt system might not be properly released and would not accept subsequent timer tick interrupts.
• [RTX Kernel]
  Corrected a problem in RTX_CONFIG.C for STMicroelectronics STR91x devices. There was a problem in the code used to disable interrupts that could cause a timer tick interrupt to occur in a protected section of RTX Kernel system. This could eventually cause a stack overflow and crash the user application.
• [TCPNet]
  Added the http_get_session function to the HTTP Server module. This function returns a HTTP Server Session instance index. It may be called from the CGI module to identify a HTTP Client which has issued a request to HTTP Server.
• [TCPNet]
  Added a PPP Server example, HTTP_DEMO, for the Keil MCB2140 Evaluation Board. This example is located found in the \KEIL\ARM\RV30\RTL\TCPNET\EXAMPLES\ folder.
• [TCPNet]
  Corrected a problem with the DHCP client. In some specific instances, the DHCP client could fail to obtain an IP address if the IP address configured in NET_CONFIG.C matched the subnet address of your local network. For example, if your local subnet is 192.168.0.* and the local IP address in NET_CONFIG.C is 192.168.0.100, the DHCP server would not return an IP address.
• [CAN Drivers]
  Added CAN drivers for the following ARM devices: Atmel AT91SAM7X, STMicroelectronics STR73x, and STMicroelectronics STR91x.
• [CAN Drivers]
  Update the CAN driver documentation.
