请教下brjtag 对flash 8bit数据宽度的使用

tom-jerry

感谢hugebird提供了brjtag源码以及对论坛新手的帮助。
在brjtag v1.8c遇到了一个麻烦，希望有谁能提供下帮助：我现有的bcm5354芯片无线猫，flash数据宽度被设计成8bits，直接使用该版本有问题。有谁可否提供下 void ejtag_write_h(unsigned int addr, unsigned int data)和static unsigned int ejtag_dma_read_h(unsigned int addr) 的对flash 8bit数据宽度实现修改？非常感谢~~

我记得新版本brjtag有个8位开关的 ，似乎是/wx8

感谢mine的指点。问题是hugebird的v1.9版本，我暂时无权下载，谁可以帮忙提供下。目前得到的v1.8c，不支持选项/wx8的。

回复 MINE 的帖子

mine,感谢您的指点。看了帖子说某些情况下有扇区被锁的情况发生。我用/showppb选项查看了，显示信息如下文。补充说明下：bcm5354芯片，S29GL128P flash（数据宽度8bit设定）。
