Is there any debug-mode to see on which step it failes? There are messages with WMT_INFO_FUNC and WMT_ERR_FUNC…how to display them?
try to add some printk’s like it’s recommended here: https://elinux.org/Debugging_by_printing (Author’s practical advice)
oh, is see the messages only in dmesg

then comes the oops listed above…and also the WMT-mesages are here…
wmt_dev.c (68,8 KB)
wmt_plat_alps.c (44,9 KB)
seems that the problem is that my cfg could not be loaded…have lowercase filename instead of uppercase (for whatever reason)
after renaming, kernel hangs…seems that kernel has crashed more than i thought…the renaming was not present after a reset…so i renamed again and started wmt_loader:
