Ethernet driver for STM32 connectivity line with port on MMstm32f107 board
Hello all,
I would like to contribute Ethernet driver for STM32 connectivity line but due
to fact that the some support from HAL package is also required. I provide port
on MMstm32f107 board.
Beside of extending stm32/var include files to provide description of Ethernet
module and adding support of new model of clock distribution in STM32
connectivity line I would like to point functionality which cause me a lot of
problem to start Ethernet driver i.e.
stm32_misc.c in function hal_variant_init() is enabled clocks for all APB
peripherals. In case of Ethernet driver it should be done :
1) after PLL configuration (switching it on this stage cause hang up of MDIO
bus)
2) only used peripherals ( switching on all APB module cause hang up of RMII
bus)
My suggestion is to move it to board dependent area i.e. hal_platform_init()
and switch only those modules which are really added to eCos image.
Best regards,
jerzy
