I agree with you here, but I don't think that I should insist on this.

Hello, Robert! I've tried what you suggested (return -EPROBE_DEFER
from rb_hardconfig_init and routerboot_init). It doesn't work.
do_one_initcall() from linux-5.4.158/init/main.
Hello, Thibaut! Here is a dmesg output as an attachment.
I've added printk into rb_hardconfig_init:
[0.806327] rb_hardconfig_init: get_mtd_device_nm returns error: -19

are linked much later in kernel
Maybe the order of init functions of SPI and routerboot

What about using register_mtd_user function: routerboot can call
rb_hardconfig_init and rb_softconfig_init when mtd subsystem notifies
it about a new mtd device? It works.

.../drivers/platf
I've tested it (on 5.4 and 5.10). On reboot I've had this kernel panic:
[ 1028.460043] Reserved instruction in kernel code[#1]:
[ 1028.465191] CPU: 0 PID: 2406 Comm: procd Not tainted 5.4.158 #0
[ 1028.471300] $ 0 : 0001
[ 1028.476702] $ 4 : 8342118c 806adf50 000
I got it! _exit macro of rb_hardconfig_init seems to cause this kernel
panic. Here is a patch.
Regards, Denis.

Subject: [PATCH] Fixes to generic: platform/mikrotik:
Thank you for your help, Thibaut. I think we've found the right way of
initializing routerboot. I've sent a v2 of the patch.

Mikrotik RB912UAG needs to be better supported in ath79, imho
and I'm working on it. Reset key, Gigabit Ethernet, mPCIe slot, UART
-- all need to be fixed. This patch adds support for reset key, next
one I'm working on will fix mPCIe slot. No ideas about how to fix
Gigabit, sigh.
Guys, please tell

Thank you, Koen! It is very good news for me this Friday night.

It's okay. The gpio-latch probe function seems to be called before the
rb91x-key probe, but it also returns
It seems that we have two options: all is good with the tunnel path,
so in this case we use default "pmtudisc noignore-df". Or something
wrong and ICMP replies with "fragmentation needed" do not come back,
so in this case we use "nopmtudisc ignore-df". But I would leave the
possibility of selective
15 matches
