Re: Olimex STM32P207/STM32P407

Thanks for the ultra-fast reply! According to the Olimex's documentation (page 30 in https://www.olimex.com/Products/ARM/ST/STM32-P407/resources/STM32-P407-Initial-release.pdf) the pins used for the sd card seems to be almost the same in SPI and SDIO: SD Card pin | SD Card meaning | SPI pin | GPIO -...

Re: Olimex STM32P204

It seems so, but it is delivered defaulted to SPI (strange). Could you explain me a bit more precisely how to "enable" SDIO on the P407? Which resistance do I need to add or remove? Also, is SDIO supported by ChibiOS on the P407? Could I expect real performance improvements with this (whi...

Re: STM32-P107: how to configure CAN

The resistor was used to see the TX signal with an oscilloscope when no transceiver was connected. Now that I've connected a transceiver, I've removed the resistor.

Re: STM32-P107: how to configure CAN

Just to be complete, here is what I've done so far. I'm trying to port the ChibiOS/testhal/STM32F1xx/CAN code to the STM32-P107 board. To do that, I've mostly done 3 things: 1- I've configured the CAN1 TX/RX pins on PD1/PD0 by defining VAL_GPIODCRL to 0x38B888B8 in the P107's board.h and by adding A...

STM32-P107: how to configure CAN

Hi, I'm new to ChibiOS and I'm trying to do some CAN experiments with an Olimex STM32-P107 board. While I have loopback mode working without problem, I struggling to remap the GPIOs I want to use as CAN1. I want CAN1_RX on PD0 and CAN1_TX on PD1. Thus I have defined VAL_GPIODCRL to 0x38B888B8 in the...
