UJA1169 in Normal Mode

[RaresTudor]

Hello, I am trying to configure the UJA1169TK/F/3 to work in Normal Mode but I am stuck at  switching the SBC from Standby mode to Normal Mode, I try to do this by writting the value 0x07 in the Mode Control register at the address 0x01. Even if I do this, when I read back the register it shows me that I am still in Stand By mode ,and the CAN communication is not working.

I want to mention that the SPI communication works fine, I have created a function to read the ID of the SBC and it returns the correct value. I have also wrote in the non volatile memory and disabled the Forced Normal mode.

Do you guys have any idea why I can switch to Normal Mode?

Thank you

After you write the register content ,do you read it again to verify?

Set  state to  nornal mode ..but fail....still at standby mode

if(status == STATUS_SUCCESS)
{
status = SBC_SetMode(config->mode);
}
/* Device was initialized successfully. */
