Hello together,
I was trying to build u-boot and spl for the arm target and tried to boot via usb-ethernet. I found an issue with one of the commit made in the early 2019, http://patchwork.ozlabs.org/patch/1024795/
When using this CONFIG_LMB the max_size or the lmb_get_free_size(&lmb, load_addr); returns 0, no matter what. And it triggers the following error, TFTP error: trying to overwrite reserved memory... I did a quick fix by adding #undef CONFIG_LMB in the file, net/tftp.c So, I would like to know why this doesn’t work as it was working before applying this patch ?
Can you add "#define DEBUG" as the first line in 'lib/lmb.c'? That should give you debug output when lmb is used.
The lmb code works by getting the RAM size, adding reserved areas and then only allowing allocations in non-reserved areay. However, the RAM size is not fully used depending on some config options and/or environment variables. There's possibly something wrong in your configuration around that.
