想在AT91RM9200 踢起 ISO7816跟USB的介面， 我公司没有买ADS 跟Multi-Ice. 但是没办法把example走起來. 那个 startup_ads.S 是用 Thumb 来写的，然后来driver 是用C 写的。 如果不走startup_ads.S, 当 driver accesses的地址 0xFFFFF440会有segmentation fault 我用了arm-linux- 跟 arm-thumb-elf 也没法把它cross-compile… 请指教. ;------------------------------------------------------------------------------ ;- ATMEL Microcontroller Software Support - ROUSSET - ;------------------------------------------------------------------------------ ; The software is delivered "AS IS" without warranty or condition of any ; kind, either express, implied or statutory.
