- Serial console:
- ---------------
- The Rock 5B has a 40-pin GPIO header. Its layout can be seen here:
- https://wiki.radxa.com/Rock5/hardware/5b/gpio
- The Uart pins are as follows:
- pin 6: gnd
- pin 8: tx
- pin 10: rx
- Baudrate for this board is 1500000.
- Login:
- ------
- Enter 'root' as login user, and the prompt is ready.

- 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
