Update for the instructions to boot Xinu? #3

Closed Kikou1998 closed 2 years ago

Kikou1998 commented 3 years ago

The entire guide could be followed and produce a working Xinu on BBB except for the uEnv.txt file: bootfile=xinu.boot boot_mmc=fatload mmc 0 0x81000000 ${bootfile}; bootm 0x81000000 uenvcmd=run boot_mmc The second address 0x81000000 is missing from the uEnv.txt original guide, which should be added if you are using the latest version of uboot. (Maybe uboot has updated some of its semantics as of June 2021? If my assumption is wrong please point it out)

How to find the address: After make in Xinu compile folder, the address will be printed as shown below:

For network boot, it seems that

ipaddr=10.10.10.10 serverip=10.10.10.1 netmask=255.255.255.0 bootfile=xinu.boot boot_mmc=tftp ${bootfile}; bootm 0x82000000 uenvcmd=run boot_mmc

the bootm should be followed by an address specifying the memory location.

Hello @Kikou1998, sorry for the delayed reply. I was taking a long vacation. Thank you for the feedback. I'll add this to the main instructions. I have seen cases where the initial memory address is different. That's why I recommend using the first step because depending on the version of u-boot or its configuration, the initial address may be different for some people. When I was first doing this, I encountered this situation too. I'll add this to the guide. Thanks again.

Sorry it took this long. I tested your results and added them to the README. Thanks again.
