Hi,
My customer plans for booting the DSP over Ethernet via SGMII-SGMII from a host MPU.
(This physical link should be OK to work in general, according to Sprugv9 section 2.4.3.3)
- Now, the question is whether the RBL initiates the SGMII in Autonegotiation (slave or master mode?) by default so that the link comes alive and carries out BOOTP as intended? I can only see the statement in Sprugy5 section 3.5 saying
"The PHY is not initialized by the RBL and it is the responsibility of the host to initialize the ethernet PHY. "
Or do we need to envision 1st booting from I2C EEPROM to setup the SGMII-SGMII link and do a 2nd bootloader similar to what is done on the EVM?
Thanks.
