Resolved! Where have all the STM32H750VBT6s gone?
I am looking 100pin STM32H750 but nobody has them in stock. Digikey, Mouser, Distrelec, TME all zero. Is there something newer or what is the problem.

Resolved! NUCLEO-L476RG access SD card using SPI
Dear allI am trying to access my SD card using SPI, I tried the code below but I couldn't get it work.is there any official tutorial about SD card of NUCLEO-L476RG?SD CARD Info: 32GB, SDHC, FAT formathttps://github.com/eziya/STM32_SPI_SDCARD
STM32F0x1 Reference Manual (RM0091 Rev 9) does not specify what the values of USART ISR TEACK and REACK bits mean when they are 0 or 1.
Compare to other bitfields, e.g., :RWU0: Receiver in active mode1: Receiver in mute modeThere is no such 0 or 1 specified for TEACK and REACK bits.Also, discussion in USART Transmitter and USART Receiver sections do not discuss this.Thanks
