cmd_eeprom: bug fix for i2c read/write Browse files The local pointer of address (i.e., addr) only gets referenced under SPI mode, and it won't be appropriate to pass only 1-byte addr[1] to i2c_read/i2c_write while CONFIG_SYS_I2C_EEPROM_ADDR_LEN > 1. 1. In U-boot's I2C ...
最近做东西遇到需要读写EEPROM的需求,利用SMBUS的方式write bye,发现效率很低,因为是利用ioctl的方式write的,所以每进行一次都需要delay 2000多us。Write 4096 bytes居然花了10秒,这不能忍啊~ SMBUS protocol 里面还有提供 i2c_smbus_write_block_data 与 i2c_smbus_write_i2c_block_data两种方法,但是貌似前面一...
请教个问题,新手刚学page write方式写EEPROM时,按官方例程,把所有数据放FIFO然后发送的方式行不通啊,FIFO只有四级深度,数据比较长时会把前面的覆盖掉。 I2caRegs.I2CCNT = msg->NumOfBytes+2; // Setup data to send I2caRegs.I2CDXR = msg->MemoryHighAddr; ...
