有哪位大佬能给我解答一下全志的一号通是什么吗？全志技术支持让我从一号通上去下载文档，给个链接，我进去不了：

现在要新支持一款spi-nand芯片，但是现在tina sdk不支持,怎么修改让其支持这款新的nandflash，复旦微的这颗：FM25S01A，有谁用过吗

wyljkl

@yuzukitsuru 都烧不进去，是不是要改什么配置？

wyljkl

现在是spi-nor/nand的存储介质，现在想要制作SD量产卡，让SD卡去升级镜像到nor/nand中，这个量产卡怎么去制作，要修改那些配置呀？麻烦各位指点下

wyljkl

@yuzukitsuru 我这边没有这个分区，介质是nandflash,只有一下几个分区：

但是，logo打包的时候还是bootresource这个分区里面。

@whycan 这样还是要重新刷写固件，是否可以不用刷写固件的方式来更换logo呢？

wyljkl

logo文件后期怎么更换呀，是不是只能重新编译打包啊

wyljkl

tina的logo可以后期更换吗？看现在直接在源码打包的时候固定了，后期不可以更换，想要更换只能重新打包烧录吗？

wyljkl

现在uboot部分都没有进入到LCD_open_flow 这个函数中，对比了驱动文件和设备树的名字也是一一致的：

@yuzukitsuru 是什么原因导致的呀？能否指点一下，非常感谢。

@smiletiger 在 D1s 调试 MIPI LCD 不亮中说：

@yuzukitsuru 我这边试了下,uboot和kernel阶段都有logo显示正常
你好，这边logo显示是在哪个部分实现的呀？

wyljkl

你好，您的问题解决了吗。我目前也是遇到这个问题

wyljkl

有思路的大家都可以提一下，感谢！

在应用层调用ioctl函数，内核获取的应用层传过去的一个结构体内容，其中有两个结构体成员内容对不上，其他的结构体成员值都是对的，这是怎么回事？
这是驱动层的IOCTL:

long disp_ioctl(struct file *file, unsigned int cmd, unsigned long arg)
{
//	printk("%s %d %s\n",__FILE__,__LINE__,__FUNCTION__);
	unsigned long karg[4];
	unsigned long ubuffer[4] = { 0 };

	struct disp_enhance *enhance = NULL;
	struct disp_smbl *smbl = NULL;
	struct disp_capture *cptr = NULL;

	}

	ubuffer[3] = (*(unsigned long *)(karg + 3));

	if (ubuffer[0] < num_screens)
		mgr = g_disp_drv.mgr[ubuffer[0]];
	if (mgr) {
		dispdev = mgr->device;
		enhance = mgr->enhance;
		smbl = mgr->smbl;
		cptr = mgr->cptr;
	}
#if defined(SUPPORT_EINK)
	eink_manager = g_disp_drv.eink_manager[0];

	if (!eink_manager)

#endif

	if (cmd < DISP_FB_REQUEST) {

	}

	}

	switch (cmd) {
	。。。。。。。。
		/* ----layer---- */
	case DISP_LAYER_SET_CONFIG:
	{
		printk("%s %d %s\n",__FILE__,__LINE__,__FUNCTION__);
		unsigned int i = 0;
		const unsigned int lyr_cfg_size = ARRAY_SIZE(lyr_cfg);

		mutex_lock(&g_disp_drv.mlock);

		break;
	}



	。。。。


	default:
