我目前在用bf702做一款音频产品，目前开发卡在BOOT，在设计中利用STM32F407作为主控，且702使用SPI2 SLAVE BOOT模式，目前在调试中SPI2_RDY（pull up to vext）一直为高，只有在stm32f4拉低dsp 的reset时为低，一直无法正确的boot，请问是否有成熟的案例作为参考，卡在boot阶段已经有一段时间了，再搞不定，项目就出大问题了，还请大神指导下slave boot如何正确操作，最好能有流程说明，附上设计原理图，SPI2_RDY（PA04）信号已经飞线到stm32…
自己做的 ADSP-BF702 的数据板子，希望使用 USB Device 模式和PC 连接获取数据，没有使用uCOS 这样系统。
没有找到ADI 关于如何使用USB的代码例子，请问在哪里有这样的示例代码？我使用的是 CCES 2.5 ，增加 USB Driver 后，发现一些些 USB API 似乎可用，在ADI 的英文技术支持区中发现该API代码使用的例子，可是针对的是 BF527 ：
adi_musbmhdrc_Init(&hUsbDevice, &InitData);…
Hi,
Do we have some dedicated lib or command to convert data between different data type for calculation? thanks.
I'm trying to compile and link my program on a BF702 using CCES 2.9.0. I would like to use the utility rom for the specific peripheral drivers (SPI/TWI/PPI/UART), but it seems, that it doesn't link against the utility rom (memory map shows huge blocks…
Hi
Does ADI has BF702 USB Device Examples without using uCOS?
I am using BF702 usb device mode, But I cann't find any examples about usb device.
please help me：（ !

Hi,The GPIO’s will be tristated when both trstb and reset_b are low and the pull-up will come into picture once we are out of reset based on the conditions listed below.If output is disabled and if IE is high and PADS_PCFG0.PUE bit is zero , then…
有点讨厌 JTAG 的14针接口，觉得有点大，希望使用SWD 接口替代 JTAG 接口，请问和ICE-1000连接最少需要哪些信号？
SWCLK
SWDIO
GND
只连接这三个信号是否就可以了？
Hi Tingting,
The internal ROM is not user programmable. It is factory programmed, it requires a minimum order and there is an NRE associated for custom ROM programmed parts. For further details please contact your local sales representative.
Best regards…
FFT Accelerator on ADSP-SC58x/ADSP-2158x is a completely new design as compared to the FFT accelerator on ADSP-214xx processors. The major differences/features of the FFT accelerator on ADSPSC58x/ADSP-2158x are:
