H= owever, the driver is embedded in Uboot. Is it possible to build a standalo= ne ext4 file system driver for UEFI, in the format of efi, just like the he= lloworld.efi. So I can use the UEFI shell command: load to load the driver = and access a ext4 partition. No, we do not support anything like that. You'll need to look at the other existing UEFI filesystem drivers instead. There's at least one, as of a few years ago. --=20 Tom --nCF0FYDDg0DL8SVv Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQGzBAABCgAdFiEEGjx/cOCPqxcHgJu/FHw5/5Y0tywFAmDtq34ACgkQFHw5/5Y0 tyyc+wv6ArrsBiMQ/NBVb83ouar0chTLW2VU79YOw4TF4cpxFf96VUgaOdOzKTC2 j/NTKuNKHG7tjFMBLOVI9U4QqCSaEe9tFQ0yV6Fw8icN+asiMAW14/IvFI3/LUf1 spLKMR3ge9+OEJdr+4Pa9gtp7NgWytlgIFwzH2PRdk+74CX2xVnsMNpYXyq1IcUT bSnt6m3OTNzCEe723UssfDmJYalYHFY3RXItaAWTuJ3vSD7cVxPhCdAzLESyu3dI L49/u0+NednsSrhDI+mntGkPtzzKKg04xorsJ+CT5tQfznx9lzl5tmUfeLebWs2q p4yRTbFOL8ekYz6ADvQMQY521NfQSihmEEDFQZyC64jGKkWvTYE4WFTjcVjaNh6O Kd7SAJpIMHjdNHVuYnPa3EDyn5Lg9vO7KG/4lLm4l8ER0bA3moXWBtZUwZJtOJ2w RhkO98nIaQwyHhxMdQPCvmtMosynChgWHScRhmR0F2AOC9PHu2Qkwg+311YtjG8W Zy917I0c =8qeH -----END PGP SIGNATURE----- --nCF0FYDDg0DL8SVv--
