    FX3/CX3(CYUSB3065) 如何配置外部FLASH

    YaXi_4492421

      我这边使用的(CYUSB3065) ,然后芯片外部挂了一个16M的FLASH,目前烧录启动,都没有问题,但是当我修改空间配置的时候,不能实现,烧录进去的时候都启动不起来。 修改的内容包含两个方面: 1. 编译的配置文件:C:\Program Files (x86)\Cypress\EZ-USB FX3 SDK\1.3\/firmware/common/fx3.ld 修改前为: I-TCM : ORIGIN = 0x100 LENGTH = 0x3F00 SYS_MEM : ORIGIN = 0x40003000 LENGTH = 0x2D000 DATA : ORIGIN = 0x40030000 LENGTH = 0x8000 修改后为: I-TCM : ORIGIN = 0x100 LENGTH = 0x3F00 SYS_MEM : ORIGIN = 0x40003000 LENGTH = 0x2E000 DATA : ORIGIN = 0x40031000 LENGTH = 0x8000 2. cyxtx.c 修改前:#define CY_U3P_MEM_HEAP_BASE        ((uint8_t *)0x40038000) 修改后:#define CY_U3P_MEM_HEAP_BASE        ((uint8_t *)0x40039000)
