回复: F133烧录nand flash失败
@chennengbiao 在 F133烧录nand flash失败 中说:
[04.680]sunxi-spinand-phy: read id failed : -110
按理应该能读出id,是不是没焊好?

回复: 解决那些千奇百怪的 Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block 错误
@maihuanyi
注意sdc0 TF卡的det引脚的电平,看下是高检测,还是低检测,如果反了Linux就检测不到卡片。 -
回复: F1C200S 触摸屏
@yanggggg
可以弱弱的回一下,这个芯片不适合干这事不?
因为处理能力真的是有点弱,软解MP3时,触摸屏就能被卡住。
你这个还得加网络协议栈吧,网卡驱动吧? -
回复: T113上的1280*800分辨率如何调试,修改dts后显示的画面不对
@xuzhenghao
有空我试一试,板子已经做好了,只是缺点时间。按以前的f1c经验,官方的tpadc还是挺好用的。

回复: T113:想在内核阶段显示logo,在uboot阶段不显示logo
@wjp2547532
如果真的要屏蔽 logo 就关闭 disp2即可:打开 device/config/chips/d1s/configs/nezha/BoardConfig.mk
找到 LICHEE_BRANDY_DEFCONF:=sun20iw1p1_uart3_defconfig
find lichee/brandy-2.0/u-boot-2018/ -name sun20iw1p1_uart3_defconfig lichee/brandy-2.0/u-boot-2018/configs/sun20iw1p1_uart3_defconfig
这里禁用 disp2 即可: lichee/brandy-2.0/u-boot-2018/configs/sun20iw1p1_uart3_defconfig

回复: 在使用riscv64-unknown-linux-gnu编译器编译sysbench后,在开发板上出现versidon'GLIBC_2.29'not found的wenti
@qq715819829
因为您的编译器和SDK里面的不是同一个,导致没有C库。如果坚持用SDK外的编译器编译,那么需要开启-static选项。 -
回复: G2D uboot阶段 logo 旋转不了?怎么办?
@hy123456
有一个简单的处理办法,uboot的开机logo用电脑软件旋转好,然后在应用程序里面做g2d旋转,其他都保持不变。 -

中文输入法和SDL2扯不到一块儿,这个功能应该是百问网韦老师团队提交的:

Usage
Enable LV_USE_IME_PINYIN in lv_conf.h.使用之前先感谢一下百问网。

回复: 开发板启动疑问
@zjbxzf
并口的RAW NAND吗?搜了一下,RAW NAND 读第一块(block)的指令基本兼容。但是在量产的产品中,建议用全志官方测试过的型号,这样稳定性比较有保证。
