通过i2c_init函数注册,然后设置i2c bus num,最后i2c probe。 目前在读写i2c设备时,提示“i2c_write:error waiting for addr ACK (status = 0x116)” 在uboot命令行通过i2c probe命令你查看设备地址,显示“valid chip addresses:”显示为空,请问这是怎么回事呢?是i2c设备注册失败吗?
When I run the i2c probe u-boot command, I'm receiving the following: i2c probeValid chip addresses: SOCFPGA_ARRIA5# What does it mean? Was no i2c devices detected on the i2c bus? Thank you! 翻译 标记: Intel® SoC FPGA Embedded Development Suite 0 ...
