ChibiOS Free Embedded RTOS

Hello, Since spring of 2016, there is a new stm32L432 family, very small package (32 pins), a lot less peripherals, but the same CM4 core with FPU than other L4. This chip seems well suited to do advanced motor control (energy efficiency, fast adc, lot of processing power, i2c, CAN, usb, serial int...

I'm trying to use the SDMMCv1 driver on the STM32L476, but doesn't appear to work with DMAv1. Is my understanding correct? So far in terms of just compilation, the issues I've found: 1) In sdc_lld_wait_transaction_end(), this code: /* Wait until DMA channel enabled to be sure that all data transferr...

Merged the patch (and adjusted all the other registries and all mcuconf.h files). I hope it is OK.

Tested LPSD1 on the Nucleo-476, works fine for me.

This seemed to work for me, but since I don't know exactly what the intent was I'm not going to claim it's a fix:



Paul.

The macro is defined as: /** * @brief Returns the request line associated to the specified stream. * @note In some STM32 manuals the request line is named confusingly * channel. * * @param[in] id the unique numeric stream identifier * @param[in] c a stream/request association word, one request per *...

Doh! That was careless of me. I'll check out the patches.

Thanks, Paul.

Here's a small tweak for I2C support as well. Paul.

Got LPUART1 working - should I raise a feature request in SF, or just leave it here?

Paul.

Got it running, finally. Was chasing your SVN commits for a day, one step behind you. GPIOv3 works fine for me. RTC works fine with the latest clock settings (LSE enabled by default) EXTIv1 needed a few tweaks - the L4 has different register names. Not sure the best way to do this, but I'll add my p...

Ok, will do.

Paul.
