Unused var in chSemResetI Topic is solved

Hi,

The fix for bug #1093 in 19.x left in chSemResetI() an unused var: cnt.
That's breaking the build when using -Werror=unused-variable...

Re: I2C4 in ST_STM32F769I_DISCOVERY Topic is solved

Thanks for looking into this.

I'm already using the latest on 19.1.x...

A question that may be stupid, but just to be sure: your test was with I2C4, correct?

Thanks!

Re: I2C4 in ST_STM32F769I_DISCOVERY Topic is solved

Giovanni, I've just compiled with -O0 as suggested. The hard fault is still there, but I couldn't see any indication on what could be causing it... I do have a fault handler but I couldn't find anything from the output. In the mean time I've stumbled on this: http://www.chibios.com/forum/viewtopic.p...

I2C4 in ST_STM32F769I_DISCOVERY Topic is solved

Hello, Was trying to use I2C4 on this Discovery board to enable the touch screen controller. It's throwing a hard fault when calling line 835 @ os\hal\ports\STM32\LLD\I2Cv2\hal_i2c_lld.c dmaStreamSetPeripheral(i2cp->dmatx, &dp->TXDR); I've tried to tweak the DMA assignments without success. If i...

Re: WSPI on STM32F769I Topic is solved

Got it! I went through all the possible configs and bumped into the clock setting. I've added the following to mcuconf.h and it's now readin the expected IDs: #define STM32_WSPI_QUADSPI1_PRESCALER_VALUE 2 Suggestion maybe this config should be made more "visible"... Thanks anyway for looki...

Re: WSPI on STM32F769I Topic is solved

I believe yes... the hardware is the STM board, so I trust it's working OK.
I've setup board.h to properly set the pin configs, including the AF values.

Also double check the commands against the ChibiOS driver.

WSPI on STM32F769I Topic is solved

Hi, I was coding a driver to use SPIFFs on the SMT32F769I-DISCO board (has a MX25L51245G). The WSPI driver, clock and DMA seem to be properly configured as I can successfully issue the RST enable (RSTEN) and RST commands. When reading the device ID (RDID) I get unexpected values: 0x30 0x88 0x06 I've...
