Hi,I am porting a project from STM32F103RE to STM32L462RE.I have an issue with the SPI slave.My problem is that in the data I send back to the master always has the first word duplicated.I found out that more people have a similar issue:https://comm...

I have read online and saw that people can use the USB custom hid class generated by the CubeIde and they get good transfer speeds.Also in the past I have worked with stm32(F103RE/L462RE) and a older usblib for custom HID and KeilIDE. I used this tog...

I have made a DFU application on the STM32L462RET6 CPU.From the CUBEIDE I set the:HSEEnable USBSelect the DFU as a Class For fs Ip.Set the app start address to 0x8008000 Set the DFU media interface to @Internal Flash /0x08000000/01*032Ka,01*480KgSet...

After a more detailed investigation it seems the reason for this issue was the fact that the time between slave enable and the output of the clock signal was too short for STM32L462.The linux master ran the clock 30ns after the ss pin was set to low....

It seems that there is a fix that could work.There is a problem with the idle state and phase of the SPI clock.The following settings worked: STM32L462 which is a salve I have CPOL and CPHA set to 0 (clock is 0 when idle and the first clock transitio...

I am having a similar issue.Do you remember what the problem was?

The main issue why most of the packets failed was in the interrupt routine for the usb.After a lot of debugging I finally looked at the irq and saw that after I transmitted any data the IRQ allways excecuted a portion of code from stm32l4xx_hal_pcd.c...

Update:Debug fix (hardware_fault handler:( not enough space so move firmware to a higher address. Release fix (DFUSe hanging in erase/write:( Fixed the Release version by erasing the entire flash not just one page and then write the firmware to it. (...

STM32L462RE - SPI slave duplicated first word

Custom HID and CUBEIDE with stm32f103/stm32l462 are too slow.

STM32L462 With USB DFU goes into Hardware fault when in the methods from usb_dfu_if.c I use the HAL_FLASHEx_Erase.
