回复: V851S I2C/TWI 损坏(xfer 错误)
@kanken6174 不建议修改引脚驱动能力,因为i2c协议要求总线为弱上拉,提高IO驱动能力会使之变成强上拉
当VCC为1.8V时,上拉电阻应选用2K
当VCC为3.3V时,上拉电阻应选用4.7K若无法正常使用,应排查走线质量与信号干扰。

回复: 全志v85x spi通信速率稍微高点,spi clk就没输出,硬件BUG?用imx6ul就没有这种问题
@sofia 没太明白,为什么软件32K频率读,控制器会是33M频率输出?你可以试下spidev_test测试是否正常

回复: 新 SDK 平台下载 D1-H/D1s SDK
@gharibi From the log i see the dl folder cannot download, cloud you please try clone it alone such as
git clone https://sdk.aw-ol.com/git_repo/D1_Tina_Open/tina-d1-h/product/tina/dl
to see what happend.
Again, I think is still network or your git configuretion issue.
Try the search early EOF or TLS packet keywords on google -
回复: t113主频问题
@wyljkl dts里面有频点表吗?试试
# 查看当前各个核频率 more /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_cur_freq | cat # 查看当前设置频点 cat /sys/devices/system/cpu/cpufreq/policy0/scaling_cur_freq # 查看系统当前可用频点 cat /sys/devices/system/cpu/cpufreq/policy0/scaling_available_frequencies # 查看当前调度策略 cat /sys/devices/system/cpu/cpufreq/policy0/scaling_governor echo performance > /sys/devices/system/cpu/cpufreq/policy0/scaling_governor

- dmesg|grep spi看下spi的打印信息
- cat /sys/kernel/debug/clk/clk_summary 看下时钟树是怎么分配的
- dump ccu中对应spi的寄存器,看下实际的分频系数是多少
