Hello,I am using a STM32H733VGT on a custom design board. On a fresh project in CubeMX, I tried to activate data cache but the autogenerated code crashes at SCB_EnableDCache(); . (nothing has been activated on the CubeMX, just the external crystal a...

Hi,I have connected a MAX-M10M module to an STM32H7 MCU ( it's custom board) by UART port. I am able to send data to GPS module and also receive config data of it but not able to receive NMEA packets. I only receive the first byte and then the HAL_...

Hello everyone,I have recently started working on a custom board which has a STM32H733VG as the MCU. various interfaces including UART, I2C, SPI and sdmmc has been implementde hardware wise to provide links between MCU and other chips on the board.I ...

Hello,we bought a STM32H757 i-EVAL and I started to play with it. So I chose the board in STMCUBE MX (version 6.12.0) and selected the default configuration. After compiling code which went well, it got stuck in the MX_SDMMC1_SD_Init function, with t...

I have coded a TCP client on a ST32F746ZGT6 and i am receiving data from a TCP sever with a rate of 50hz and a packet size of 1460 bytes through ethernet. as part of my TCP client in tcp_client_handle function, i am extracting only 4 bytes of the rec...

Hi,yeah, that's the case, unexpectedly if I put a breakpoint after these two (SCB_EnableICache() and SCB_EnableDCache()) , I'll reach HAL_Init(). (I just figured this out).Could you tell me why is it behaving like this? Thanks a lot for your help.

Thanks a lot for that.BTW, is it necessary to enable Dcache to activate ethernet for this MCU?

Hi,tried that, no difference, it stuck in the activation function of data cache.Would you explain me what are suspicious about? Thanks a lot for you help

Hi I think so , here is my ioc file:Thanks

It was a hardware issue, due to some reasons the module was in safe boot mode and not transmitting the NMEA sentences. Thanks for your comments anyway.
