Other Parts Discussed in Thread: USB2ANY
Dear Team,
How does LMK05318 read and write the internal EEPROM register from I2C?
The problem currently encountered is that the value can be read, but it cannot be written.
Verify EEPROM image revision (address byte #11, 0xb) read/write test steps are as follows
1. First read 0xb=0 with USB2ANY tool
2. The system reads I2C 0x66 0xb=0
3. Write 1 to 0xb with USB2ANY tool
4. USB2ANY reads 0xb=1
5. System reads I2C 0x66 0xb=1 ==>read ok
6. System write I2C 0x66 0xb=0
7. The system reads I2C 0x66 0xb=1 ==>write fail
Is there any special format for write? I want to confirm whether it is a cmd problem or a protocol problem.
BR
Kevin
