I just ported my project from freertOs to ChibiOs, it work well exept one thing, the spi bus.
I use a ssd1322 based Oled display with spi1, the spiStart function freeze.
this is the stack :

I have started from the USB/WEB/LWIP demo
HAL_USE_SPI is set to TRUE
STM32_SPI_USE_SPI1 is set to TRUE
So, something use the DMA 2 stream 0 ? I don't find what.
