Hi Olivier, Thanks for your mail.
I have a SerialPortLib which tries to configure Serial controller specific to my board (so *no* 'SerialPortLib' pointing to 'MdePkg/Library/BaseSerialPortLibNull/BaseSerialPortLibNull.inf' in my DSC). I am getting the UEFI firmware .. banner at the very start. I will now try to add some SerialPortWrite() before calling GetSectionFromAnyFv().
