I am trying to communicate with an SD card using SPI.I have found a library, that can work on an STM32g031f6, but if I try to do the same on an STM32g030j6, it crashes/resets when it calls the function "__HAL_SPI_ENABLE" in "stm32g0xx_hal_spi.c".I ha...

I am trying to directly write to some STM32G03 chips.I have an "STM32G030J6M6" and a "STM32G031F6P6" but I am unable to write to them.I can connect to them, using the CubeProgrammer, but only in "Hot plug" mode, and when I try to write anything, like...

I am unable to use other pins for the SPI configuration, as both SPI 1&2 needs pin 8, but I will try and see if I can disable the reset pin.

I am trying to do the same thing. Where exactly did you find the NRST and what did you change it to?I can see something called "NRST_MODE" in the REG viewer, is that it? What did you change it to?

I have attached an image of the CSR registers, they don't seem to change at any time.The power for the chip, comes from a Constant Voltage power supply at 3.3v, so that shouldn't be an issue.I am not quite sure how to check the watchdog status.

That worked.Nowhere I looked, could I find that I needed to short those pins, but now I can talk to the chip.Thank you very much.

The voltage is not being pulled down.When giving the board 3.3v, I can measure the correct voltage on the target (3.3v).Using the VAPP pins on the programmer, it only outputs 2.4v, which is the same as I measure on the target.The CubeProgrammer says ...

HAL_SPI_ENABLE causes crash/reset on STM32G030J6

I can't write to my STM32G03 when connect in Hot plug mode, and I get DEV_TARGET_CMD_ERR whenever I try to connect in Normal mode.

Re: Can the STM32G030 nRST pin disabled, or be used as GPIO?
