STM32H7RS | H7S3L8 Core Freeze XSPI + DCACHE in Bootloader
Hi,I am experiencing a core freeze issue on STM32H7S3L8 MCU, as described below.UPDATE 1: Most probably Data Cache is the main culprit, closing Data Cache in bootloader solves the problem. Application code Enables Data Cache and we have never observe...
RM0316 (STM32F303) - COMP2_INP_DAC
In RM0316 rev.10, in Table 109. COMP register map and reset values, bit 1 of COMP2_CSR is marked COMP2_INP_DAC, whereas the STM32F303 are not supposed to have this bit (only STM32F301/302x6/8 do) - probably a copy/paste artefact/relict.Can ST please ...
Resolved! STM32U5 OSPI communication with IS66WVO32M8 ISSI OctalRAM failing read operations
Hello,I am working with the STM32U585AI using OCTOSPI2 to interface with the IS66WVO32M8 32 Mbyte ISSI OctalRAM. Currently I am facing an issue of read operations failing for both register and memory access, both in and out of OPI DTR mode. Register ...
