- Ethernet:
- iperf3 is included with the Krogoth Yocto BSP. With UDP, this command reports much lower bandwidth than expected when compared with iperf command.
- eMMC:
The following error messages may appear in Linux when running in HS400 mode. This is expected with high speed SD card protocols, and is not an actual error. This patch changes the message to debug level instead: https://patchwork.kernel.org/patch/8122111/
Code Block mmcblk2: error -110 sending stop command, original cmd response 0x900, card status 0x400900 mmcblk2: retrying because a re-tune was needed
- Flashing with U-Boot: fsl-image-gui-imx7d-phyboard-zeta.sdcard image is too large to be loaded into memory (1GB) from u-boot. Workaround: Partition and flash eMMC from Linux instead. See Quickstart for instructions.
