手上一块6745的板子,将stm32的程序擦除后,dsp不能正常连接,这是因为没有boot的原因吗?看了一下原理图,这块板子的boot mode是spi1 slave mode,那么stm32又如何控制dsp正常boot呢?

你好,这是连接不上多提示的错误:
Error connecting to the target: Error 0x80000240/-1146 Fatal Error during: Initialization, OCS, Invalid data was scanned by the emulation controller. Verify the board setup to make sure the scan chain is properly defined. If the setup is correct, then RESET EMULATOR. This will disconnect each target from the emulator. The targets should then be power cycled or hard reset followed by an emureset and reconnect to each target.
你好,现在仿真器可以正常连接了,我在用arm建立与dsp的连接时又遇到了一点问题,在查询SWS,POS,OS这三步时,因为spi是16位发送,所以通常一个32位,比如POS 0x5853590B的高16位和低16位总需要重复执行很多次才能正确匹配,而且在匹配N时(就是POS中的第二步),我需要循环发送两次0x00000002才能匹配(并不是不成功就从SWS整个重来,就仅仅是发两遍0x00000002),我想问这样子算是匹配成功吗?我在建立连接后发送ais,连接DSP发现寄存器并没改变,也就是说没有loader成功,请问要如何改进呢?请多多指点~~在此谢过。
