Issues:

|

|
|
|
|
WiFi
|
|
----
|
|
The custom Radxa kernel provides custom code to support WiFi. However,
|
|
that code does not compile with GCC 12, which is the current default
|
|
version in buildroot. Hence, the WiFi kernel drivers are disabled, until
|
|
the issues get fixed (if ever). If they are desperately needed, one may
|
|
apply the following workaround, as long as buildroot still supports GCC
|
|
version 11:
|
|
|
|
1. Set GCC version 11, by adding the following line to
|
|
configs/rock5b_defconfig:
|
|
|
|
BR2_GCC_VERSION_11_X=y
|
|
|
|
2. Re-enable custom WiFi drivers by removing the following line from
|
|
board/radxa/rock5b/linux.fragment:
|
|
|
|
# CONFIG_WL_ROCKCHIP is not set
|
|
|
|
Rockchip FIQ Debugger
|
|
---------------------
|
|
The custom kernel used for this board features an FIQ debugger, which
|
|
can be activated by typing "fiq" on the serial interface. As this can be
|
|
annoying if a user wants to type these charakters and it is not needed
|
|
for most users, this board support disables the FIQ debugger by default.
|
|
To re-enable the FIQ debugger follow the steps:
|
|
|
|
1. In board/radxa/rock5b/rock5b.dts set the status property of the
|
|
fiq_debugger node to "okay" and set the status property of the uart2
|
|
node to "disabled"
|
|
|
|
2. Re-enable the fiq debugger module by removing the following line
|
|
from board/radxa/rock5b/linux.fragment:
|
|
|
|
# CONFIG_ROCKCHIP_FIQ_DEBUGGER is not set
|
