Hello Jonathan, the only place where I can find a string 'error frame:' is in drivers/net/fec_mxc (line 885).
It indicates that any of the following conditions was met Frame length violation Nonoctet align frame Receive BD status: CRC error Receive FIFO overrun Receive BD status: Frame is truncated A receive FIFO overrun can be expected if network packages are not processed. With the network patches we check if a package is available quite often. I think that printf should be replaced by debug here like in other drivers (drivers/net/ethoc.c:383). Further drivers that will print an error message if an overrun occurs are: drivers/net/mvneta.c:952 (Marvell Armada 385 network interface) drivers/net/mvpp2.c:4458 (Marvell Armada 375/7K/8K network interface) Best regards Heinrich On 10/15/2017 04:36 AM, Jonathan Gray wrote: > After the recent changes to add SimpleNetworkProtocol to efi_loader > when booting off mmc via an efi payload that doesn't use > SimpleNetworkProtocol U-Boot's fec_mxc driver will now display > various "error frame" messages. > > U-Boot SPL 2017.11-rc1-00277-g7b342d8c5d (Oct 15 2017 - 12:55:50) > Trying to boot from MMC1 > > > U-Boot 2017.11-rc1-00277-g7b342d8c5d (Oct 15 2017 - 12:55:50 +1100) > > CPU: Freescale i.MX6Q rev1.5 996 MHz (running at 792 MHz) > CPU: Extended Commercial temperature grade (-20C to 105C) at 32C > Reset cause: WDOG > Board: MX6 Cubox-i > DRAM: 2 GiB > MMC: FSL_SDHC: 0 > No panel detected: default to HDMI > Display: HDMI (1024x768) > In: serial > Out: serial > Err: serial > Net: FEC > Hit any key to stop autoboot: 0 > switch to partitions #0, OK > mmc0 is current device > Scanning mmc 0:1... > reading /imx6q-cubox-i.dtb > 37669 bytes read in 20 ms (1.8 MiB/s) > Found EFI removable media binary efi/boot/bootarm.efi > Scanning disks on usb... > Scanning disks on mmc... > MMC Device 1 not found > MMC Device 2 not found > MMC Device 3 not found > Scanning disks on sata... > Found 6 disks > reading efi/boot/bootarm.efi > 67372 bytes read in 32 ms (2 MiB/s) > ## Starting EFI application at 12000000 ... >>> OpenBSD/armv7 BOOTARM 1.0 > error frame: 0x8f57ec40 0x00003d74 > error frame: 0x8f57ec40 0x00007079 > error frame: 0x8f57ec40 0x00006964 > error frame: 0x8f57ec40 0x00006f6f > error frame: 0x8f57ec40 0x0000726f > error frame: 0x8f57ec40 0x00002074 > error frame: 0x8f57ec40 0x00006f6f > boot> error frame: 0x8f57ec40 0x00007465 > error frame: 0x8f57ec80 0x00007220 > error frame: 0x8f57ec80 0x00006374 > error frame: 0x8f57ec80 0x00007261 > error frame: 0x8f57ec80 0x00006f64 > error frame: 0x8f57ec80 0x0000385f > error frame: 0x8f57ec80 0x00002d31 > error frame: 0x8f57ec80 0x00006431 > error frame: 0x8f57ec80 0x0000302d > error frame: 0x8f57ecc0 0x00003233 > error frame: 0x8f57ecc0 0x00006e49 > error frame: 0x8f57ecc0 0x00006e6f > error frame: 0x8f57ecc0 0x00007472 > error frame: 0x8f57ecc0 0x0000622c > error frame: 0x8f57ecc0 0x00006f6c > error frame: 0x8f57ecc0 0x00003030 > error frame: 0x8f57ecc0 0x00003030 > error frame: 0x8f57ed00 0x0000645f > error frame: 0x8f57ed00 0x00006966 > error frame: 0x8f57ed00 0x0000642f > error frame: 0x8f57ed00 0x00006274 > error frame: 0x8f57ed00 0x0000746e > error frame: 0x8f57ed00 0x00006466 > error frame: 0x8f57ed00 0x00006d69 > error frame: 0x8f57ed00 0x00006f62 > error frame: 0x8f57ed40 0x00000062 > error frame: 0x8f57ed40 0x0000463d > error frame: 0x8f57ed40 0x00006461 > error frame: 0x8f57ed40 0x00003336 > error frame: 0x8f57ed40 0x0000383a > error frame: 0x8f57ed40 0x00007464 > error frame: 0x8f57ed40 0x00007830 > error frame: 0x8f57ed40 0x00003030 > error frame: 0x8f57ed80 0x00006464 > error frame: 0x8f57ed80 0x00003831 > error frame: 0x8f57ed80 0x00003d68 > error frame: 0x8f57ed80 0x00006666 > error frame: 0x8f57ed80 0x00006461 > error frame: 0x8f57ed80 0x00003030 > error frame: 0x8f57ed80 0x00006674 > error frame: 0x8f57edc0 0x00003678 > error frame: 0x8f57edc0 0x00002d78 > error frame: 0x8f57edc0 0x00006966 > error frame: 0x8f57edc0 0x0000313d > error frame: 0x8f57edc0 0x00000030 > error frame: 0x8f57edc0 0x0000657a > error frame: 0x8f57edc0 0x0000693d > error frame: 0x8f57ee00 0x00002420 > error frame: 0x8f57ee00 0x0000616e > error frame: 0x8f57ee00 0x00004d55 > error frame: 0x8f57ee00 0x00005241 > error frame: 0x8f57ee00 0x00006574 > error frame: 0x8f57ee00 0x00007261 > error frame: 0x8f57ee00 0x0000203d > error frame: 0x8f57ee00 0x00007420 > > booting sd0a:/bsd: 3926840+164812+561396|[283058+90+521360+245040]=0x571a54 > Writing to MMC(0)... done > > OpenBSD/armv7 booting ... > _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
