Dear Matt/All: I enabled Tianocore debug in coreboot and the serial debug dump showed me Tianocore was trying to open a ATA / ATAPI device and was getting stuck there, so, i disabled a still driverless "ATA" device devicetree until I attach some driver.
After flashing this change, the first boot/reboot will go without delay (normal fast tianocore boot) but after the second boot/reboot the serial dump shows the following long and repeated loop of the following: Added variable: 0x0, val size: 0 Found variable: key size: 0x0, val size: 0 Added variable: 0x0, val size: 0 Found variable: key size: 0x0, val size: 0 Added variable: 0x0, val size: 0 Found variable: key size: 0x0, val size: 0 Added variable: 0x0, val size: 0 Found variable: key size: 0x0, val size: 0 Added variable: 0x0, val size: 0 Found variable: key size: 0x0, val size: 0 Added variable: 0x0, val size: 0 Found variable: key size: 0x0, val size: 0 Several minutes later boots normal. If someone here knows how to fix it or suspect which could be the reason please let me know. I will ask for help in the EDK2 mail list too. Thank you, Jose Trujillo. > are you getting serial output via it from coreboot?
