各位好,我想使用IMX6ul的SNVS_TAMPER0 作为GPIO功能,控制LED灯,开始使用CPU型号是MCIMX6G2DVM05AA ,控制没有问题,但是后来CPU型号换成MCIMX6G3DVM05AA 这个是带加密的功能,同样的程序结果控制不了,请问软件上有区别还是硬件要调整呢,请给我点建议,谢谢!

Hi igor

我在uboot下面使用了fuse read 0 3

Reading bank 0:

Word 0x00000003: 000000c8

上面的提示是[21 20]位是00,没有使用gpio功能,我可以使用fuse prog 0 3 003000c8 这个命令把SNVS_TAMPER0 到SNVS_TAMPER9都设置为GPIO吗?
