回复: rs485的设备树怎么修改发布在 其它全志芯片讨论区
@awwwwa 你好。这两种设备树的485定义，我在5.4内核和5.10内核中都没有找到响应的定义，请问这是在哪个驱动代码里面实现的呢？我在a40-i的5.10内核，甚至没有找到sunxi-uart.c这个文件，这个正常吗？

回复: R328-S2使用W25N02问题发布在 其它全志芯片讨论区
@whycanservice 我对比了正常的flash芯片（支持列表里面的），这里也是会打印这个log，到了打印“SPI nand ID: 22aaef 0”之后，log才不一样。我看晕哥在其它帖子上说d1s/d1h支持了W25N02，那这个配置参数能发一下吗？

R328-S2使用W25N02问题发布在 其它全志芯片讨论区
我在R328-S2上使用W25N02KVZEIR，在uboot-id.c文件添加这个器件的支持，但是烧录的时候失败了。

回复: T113-S3 rgb屏幕调试问题发布在 其它全志芯片讨论区
@whycanservice 时序参数问了屏幕厂家，也没有。相位调了一下没变化。之前是用stm32的fsmc驱动的。发现有rgb，所以看看用t113看能不能驱动。资料太少，还是放弃了。已买其它屏幕。谢谢了。

T113-S3 rgb屏幕调试问题发布在 其它全志芯片讨论区
请教各位大佬，你们调试屏幕的时候有出现过图片这个情况吗？这是colorbar显示的效果，其它图片的话就是花屏。这大概是哪里的问题？
另外用逻辑分析仪录得de dclk hsync vsync 的波形，
这是不是这几个时钟完全不对？ -

spi我也遇到过卡死的问题，不是这个大佬的代码，是代理给的代码。resetfifo后，没等reset结束，直接读数据，就会卡死。我把它改成resetfifo后，判断一下reset完成再进行下一步就不会卡死了。

@yuzukitsuru 谢谢大佬。再请教一下，出现这个报错的情况，是将一个分区的文件，解压到另一个分区的时候出现的，两个分区都是fat格式的。储存用的是mmc，这个brcmfxxx是WiFi的驱动。大佬有解决思路或者调试方向可以指引一下吗

回复: 全志芯片如何提高GPIO触发中断精度？发布在 其它全志芯片讨论区
这个问题之前也遇到过。就普通的按键，有时候会失灵。修改采样时钟为24m就没问题了。配置的上升沿和下降沿触发，难道需要捕获到上升沿和下降沿才会触发中断吗？

回复: T113 Tina reboot 无法重启发布在 D1系列-RISC-V
longon的sdk，也遇到过经常reboot卡死，主要是在充电发热的时候，后面把psci.c里面psci_sys_reset函数的else里面的屏蔽掉，然后就会执行看门狗重启，就不会卡死。也不知道什么问题。
这个问题需要你自己研究一下了
