In addition +to the peripherals provided by bf527 the board has a temprature sensor, +accelerometer and power module connected via I2C. It also has LCD interface, +Card reader interface. + +The analog device bf52X family of processors are different from the bf53x range +of processors. This port supports the additional features that are not +supported by the blackfin 53X family of processors. + +The TLL6527M does not use the interrupt module used by the bfin 53x since it has +an additional system interrupt controller isr registers for additional lines. +On the 53X these line are multiplexed. +The centralized interrupt handler is implemented to use lookup tables for +jumping to the user ISR. For more details look at files implemented under +libcpu/bfin/bf52x/interrupt/* + +This port supports only the uart peripheral. The uart is supported via +polling, DMA, interrupt. The uart file is generic and is common between the +ports. Under bsp configure.ac files +* change the CONSOLE_BAUDRATE or to choose among different baudrate. +* Set UART_USE_DMA for UART to use DMA based transfers. In DMA based transfer + chunk of buffer is transmitted at once and then an interrupt is generated. +* Set CONSOLE_USE_INTERRUPTS to use interrupt based transfers. After every + character is transmitted an interrupt is generated. +* If CONSOLE_USE_INTERRUPTS, UART_USE_DMA are both not set then the port uses + polling to transmit data over uart. This call is blocking. + +TLL6527 specific file are mentioned below. +===================================== +c/src/lib/libcpu/bfin/bf52x/* +c/src/lib/libbsp/bfin/TLL6527M/* + + +The port was compiled using +=========================== +1. bfin-rtems4.11-gcc (GCC) 4.5.2 20101216 + (RTEMS gcc-4.5.2-3.el5/newlib-1.19.0-1.el5) +2. automake (GNU automake) 1.11.1 +3. autoconf (GNU Autoconf) 2.68 + + +The port was configured using the flags +========================================== +--target=bfin-rtems4.11 --enable-rtemsbsp=TLL6527M --enable-tests=samples +--disable-posix --disable-itron + + +ISSUES: +Could not place code in l1code (SRAM) because it was not being loaded by the +gnu loaded.
