CC3200的RAM容量可以外部扩展吗?
CC3200内部RAM容量最大值只有256K,可以外部扩展吗?如果可以,希望能提供参考资料,希望TI员工能协助解决,谢谢!
xian fei ,
很遗憾,不能外部扩展,因此没有参考资料。
你好,目前的CC3200的RAM不支持外部的扩展,不过下一代TI的wifi产品有内置的Flash版本,代码量就不受限与内部RAM的限制。
请问内部ram是怎么划分的呢
Production version of CC3200 will have 256Kbyte of RAM.16KB is shared with bootloader.
CC3200 does not have the user application flash memory so that we need to use internal RAM for code memory and share the 256KB RAM
SRAM size of 240KB for CC3200 ES 1.33 device
On CC3200 the code is always loaded from the serial flash into SRAM by bootloader and then executed in SRAM
Your program ( code + stack size + dynamic memory needed ) should be within 240 KB (lower 16 KB is used by CC3200 boot-loader)
If you want to use the the lower 16 KB also, please refer to section "6.1.2 Boot Loader / User Application – Sharing MCU RAM " in CC3200-Programmers_Guide.pdf and 'camera_application' from the SDK
The code can't be run from sFlash directly, CC3200 boot-loader loads the application in full from sFlash to SRAM before executing.
可以扩展spi flash
原来是这么换分的,感谢您
给后来的人提个醒,可能涉及到字节对齐的问题,SRAM_DATA的长度需要是1024的整数倍
感谢分享,如果问题解决了,建议将问题置为已解决,谢谢!
啊,我找了找,不知道在哪设置已解决
