最新RTOS版SDK overlap问题

[zhangjinliang]

你好：

我把代码从旧版本的SDK切换到最新的RTOS版本的SDK上。初始化HSPI的overlap后（如下），
SET_PERI_REG_MASK(0x3ff00028, BIT(7));
//set higher priority for spi than hspi
SET_PERI_REG_MASK(SPI_EXT3(SPI), 0x1);
SET_PERI_REG_MASK(SPI_EXT3(HSPI), 0x3);
SET_PERI_REG_MASK(SPI_USER(HSPI), BIT(5));
做了以上初始化后，用spi_flash_read这个接口去访问SPI外挂的FLASH，无法返回，卡住一段时间后异常复位，异常信息时乱码。
如果没有以上初始化overlap的过程，访问时OK的。同时旧版本也是OK的。

麻烦帮忙定位一下问题所在？

请乐鑫的FAE帮忙验证一下， 最新的RTOS sdk是否有上述问题！！多谢

我使用的1.3.1 2016-11-16的RTOS SDK有同样的问题，是否RTOS SDK不支持overlap?

您好，

麻烦基于 ESP8266_RTOS_SDK_V1.4.0 更新附件 lib。

如果您的问题仍未解决，请再告知。

感谢您对 ESP8266 的关注！

Hello,

I may be experiencing this very same problem with the NONOS SDK V1.5.3 (PlatformIO/Arduino).
Whenever the statement

Code: Select all

SET_PERI_REG_MASK(SPI_EXT3(SPI), 0x1)

is executed, subsequent calls to SPIFFS (e.g. file.open) fail and cause an exception.
Was the solution to this problem ever added to the NONOS SDKs?
What exactly does the above statement do? I understand that the SPI port priorities are set, but the exact definition of the the lower two bits of the SPI_EXT3 register is unclear to me.
