Bugs or limitation¶
- all builds suffer from minor problems with specific mPCIe combinations. If you run into problems check this test matrix for some known working/not working combinations.
Converting mPCIe to mSATA¶
- To convert mPCIe to mSATA you have to enable the corresponding patches in u-boot-mvebu. Afterwards rebuild u-boot with our build system and write the new u-boot to your boot medium. If you need assistance ask in the forum.
Notes¶
- In case you ever run into troubles and ask for help in the forums please ensure to provide a serial console log (UART adapter on board accessible through Micro USB with 115200/8/N/1 settings)
- The boards can boot from various sources that are adjustable with a DIP switch. Comprehensive information about the necessary preparations available here.
