Hi

I was not able to read the last block of my sd card

(the gpt backup block) without the following

diff --git a/lib/efi_loader/efi_disk.c b/lib/efi_loader/efi_disk.c index d0aad0252a..ea9d763072 100644 --- a/lib/efi_loader/efi_disk.c +++ b/lib/efi_loader/efi_disk.c @@ -147,7 +147,7 @@ static efi_status_t EFIAPI efi_disk_read_blocks(struct efi_block_io *this,             (uintptr_t)buffer & (this->media->io_align - 1))                 return EFI_INVALID_PARAMETER;         if (lba * this->media->block_size + buffer_size > -           this->media->last_block * this->media->block_size) +           this->media->last_block * this->media->block_size + this->media->block_size)                 return EFI_INVALID_PARAMETER;

Is my math wrong or is my patch correct?

With the patch the my efiloader can read the gpt backup block correctly,

Thanks
