AntonLS 0:28ca4562fe1a 2 * TA test
AntonLS 0:28ca4562fe1a 3 *
AntonLS 19:afcbb425b3cf 4 * Updated for New TA Baseboard (rev Aug-Nov 2015.)
AntonLS 19:afcbb425b3cf 5 *
AntonLS 11:d3aa5fca2330 6 * TODO maybe have a mode where the serial port I/O can be swapped,
AntonLS 11:d3aa5fca2330 7 * such that what the nRF generates is sent out the serial port,
AntonLS 11:d3aa5fca2330 8 * and what comes in the serial port goes into the nRF.
AntonLS 11:d3aa5fca2330 9 * Maybe could use the now-unused CTS pin for that.
AntonLS 13:28332f65d14b 10 *
AntonLS 13:28332f65d14b 11 * Using
AntonLS 13:28332f65d14b 12 * rev 327 of BLE_API
AntonLS 13:28332f65d14b 13 * rev 102 of nRF51822 w/ modification--See below
AntonLS 15:b86c4b798aa1 14 * rev 97 of mbed lib
AntonLS 15:b86c4b798aa1 15 * corresponding to:
AntonLS 15:b86c4b798aa1 16 * rev 493 of mbed-src w/ modification to targets/hal/TARGET_NORDIC/TARGET_MCU_NRF51822/serial_api.c
AntonLS 19:afcbb425b3cf 17 * so things compile properly.*
AntonLS 19:afcbb425b3cf 18 * * Now using $Sub$$UART0_IRQHandler to override UART0_IRQHandler without needing to use lib source.
AntonLS 13:28332f65d14b 19 *
AntonLS 31:a6110950f385 20 * *** Now using mbed-src again to modify startup code to use full 32k RAM on QFAC part 20160104 ALS
AntonLS 31:a6110950f385 21 * while still using RBL BLE Nano as a target:
AntonLS 31:a6110950f385 22 * Copied files nRF51822.sct and startup_nRF51822.s
AntonLS 31:a6110950f385 23 * from targets/cmsis/TARGET_NORDIC/TARGET_MCU_NRF51822/TOOLCHAIN_ARM_STD/TARGET_MCU_NORDIC_32K
AntonLS 31:a6110950f385 24 * to targets/cmsis/TARGET_NORDIC/TARGET_MCU_NRF51822/TOOLCHAIN_ARM_STD/TARGET_MCU_NORDIC_16K
AntonLS 31:a6110950f385 25 * (Stomping the 16k settings w/ 32k settings.)
AntonLS 31:a6110950f385 26 *
AntonLS 13:28332f65d14b 27 * Changed
AntonLS 13:28332f65d14b 28 * nRF51822/nordic/pstorage_platform.h PSTORAGE_MIN_BLOCK_SIZE changed from 0x010 to 4.
