I2c burst read may failed due to misoperation of ir3570a(A DC-to-DC converter IC). As #2966, there are 3 more models have this symptom, as7326-56x, as7726-32x, and as9716-32d. Also correct typo of naming on as7816-64x and as7716-32x. Signed-off-by: roy_lee roy_lee@accton.com What I did Disabling i2c function of ir3570a which may failed i2c tranfer to others. Close channel of mux after data transfered. How I did it Identify version of ir3570, if it's ir3570a, disable its alias i2c address. Enable parameter of driver i2c_mux_pca954x to close channel on after every access. How to verify it Write 08 to offset 0xcf of systom eeprom and execute i2c block read. It will return error. plug-in several transceivers and run "show interfaces transceiver presence" and "sfputil show presence". You may see the different result. (But doing this requires updated xcvrd). Signed-off-by: roy_lee <roy_lee@accton.com> |
