!arch/stm32: unify and commonize stm32_uid for all STM32 families.#19295
Merged
Conversation
Replace the per-family stm32_get_uniqueid() implementations and the two IP-versioned common variants with a single generic byte-array reader, arch/arm/src/common/stm32/stm32_uid.c. BREAKING CHANGE for STM32 M0 families: stm32_get_uniqueid() now always takes a uint8_t[12] buffer. Out-of-tree Cortex-M0 code that used the previous prototype "void stm32_get_uniqueid(uint32_t *uid)" must change its buffer to "uint8_t uniqueid[12]". Signed-off-by: raiden00pl <raiden00@railab.me>
