STM32H573 OTFDEC Images: Bind Ciphertext to the Physical Address and Region ID
Why does an encrypted external-flash image stop decrypting correctly after relocation even when its key and nonce are unchanged?

STM32G474 Fast Flash Programming: Verify the Row Size and Erase Scope Before Writing
Why can G474 fast programming fail after a page erase or stop partway through a seemingly valid block, although ordinary doubleword programming works?

Yocto devtool deploy-target: Supply Runtime Dependencies Even When the Recipe Declares Them Correctly
Why does an application deployed with devtool fail to find a shared library that its Yocto recipe correctly declares and packages?
-
Yocto Configuration Fragments: Trace an Enabled Build Setting Through OE_FRAGMENTS and toolcfg.conf
Why can a top-level Yocto configuration fragment appear in list-fragments without affecting the build, or remain active after a setup command is no longer in the shell history?
-
STM32G474 FDCAN Receive Filters: Close the Nonmatching-Frame Path Explicitly
Why do unrelated CAN identifiers still reach G474 FIFO0 after firmware installs a narrow acceptance filter?
-
STM32G474 DAC Sample-and-Hold: Budget Voltage Droop While the Output Is Tri-Stated
Why does a G474 DAC output drift in sample-and-hold mode even when firmware never changes its digital code?
-
Yocto cleanall and Shared Downloads: Explain an Unpack Failure After Cleaning a Native Variant
How can cleaning recipe-native delete the source archive still expected by the target recipe even though that target’s do_fetch stamp survives?
-
STM32H750 RNG Seed Errors: Drain the Recovery Pipeline Before Returning Random Words
Why is clearing SEIS insufficient to resume an H750 random-number API safely after a seed error?
-
STM32G474 Hardware CRC: Match Write Width and REV_IN Grouping to the Intended Byte Stream
Why does a G474 hardware CRC change when firmware replaces byte writes with packed word writes even though the payload bytes are unchanged?
-
STM32G474 FDCAN Transmit Order: Choose FIFO Arrival Order or Queue Identifier Priority
Why can a later low-ID frame wait behind an earlier high-ID frame in one G474 configuration but overtake it in another?
