Watch out for an out-of-date STM32 Standard Peripheral library

ST has newer versions of the STM32 standard peripheral library that aren't being released. If you search on the website you'll find v3.5.0, dated as released 11-March-2011. But, if you download the STM32 USB-FS_Device driver package you can see that this includes a much newer STM32 standard peripheral library, v3.6.1 dated 05-March-2012.

There are some quite important fixes between v3.5.0 and v3.6.1:


V3.6.1 / 05-March-2012
Main Changes

  • All source files: license disclaimer text update and add link to the License file on ST Internet.

V3.6.0 / 27-January-2012
Main Changes

  • All source files: update disclaimer to add reference to the new license agreement
  • stm32f10x_sdio.c
    • SDIO_SetPowerState() function: fix POWER register configuration, only one access (for read or write) is allowed
  • stm32f10x_usart.h/.c
    • Update procedure to check on overrun error interrupt pending bit, defines for the following flag are added:
    • USART_IT_ORE_RX: this flag is set if overrun error interrupt occurs and RXNEIE bit is set
    • USART_IT_ORE_ER: this flag is set if overrun error interrupt occurs and EIE bit is set
  • Remove IS_USART_PERIPH_FLAG macro (not used)
  • stm32f10x_rtc.c
    • Update RTC_GetCounter() function to fix issue when reading the RTC counter registers (CNTL & CNTH registers) and the counter rolls over
    • stm32f10x_flash.c
  • Flash keys moved from to stm32f10x.h file
  • stm32f10x_tim.c
    • TIM_UpdateRequestConfig(): correct function header's comment 
  • stm32f10x_exti.h
    • EXTI_InitTypeDef structure : for “EXTI_Trigger“ member, change “@ref EXTIMode_TypeDef”  by  “@ref EXTITrigger_TypeDef”
It would be nice if ST could release the latest STM32 peripheral library as a standalone package. I'm tempted to put up a github of the v3.6.1 library. The license appears to allow for that...

UTM (qemu on OSX) only boots into uefi shell after installing Ubuntu 22.10 (solved!)

I've been meaning to try out running Linux and Windows virtual machines on my x86 MacBook Pro using qemu . I've been using Parallels for several years. Parallels is a nice application and works well but I'm always getting bugged to purchase upgrades. Parallels provides free updates on minor version upgrades only, say 13.0 to 13.1. With so many prompts to purchase upgrades it feels like Parallels could release a bit more minor versions and a bit fewer major versions. Rather than just purchase an upgrade to Parallels I figured I'd try out qemu via the UTM application . UTM wraps qemu with a helpful gui and comes as a packages Mac application. And UTM supports both x86 and M1 systems (as qemu also supports these systems). Creating an Ubuntu VM with UTM didn't go as smoothly as with VirtualBox or Parallels but it was the settings I chose that messed me up. Here are two things I ran into when installing Ubuntu on UTM. #1. Configure the qemu instance to use a 'Display...

Debugging an imprecise bus access fault on a Cortex-M3

This information may apply to other cortex series processors but is written from practical experience with the Cortex-M3. Imprecise bus access faults are ambiguous, as noted by the term "imprecise". Compared to precise bus errors, imprecise errors are much trickier to debug and especially so without a deep understanding of arm processors and assembly language. Imprecise and precise flags are found in the BusFault status register, a byte in the CFSR (Configurable Fault Status Register). BusFault status register bits The definition for imprecise and precise bits is: [2] IMPRECISERR Imprecise data bus error: 0 = no imprecise data bus error 1 = a data bus error has occurred, but the return address in the stack frame is not related to the instruction that caused the error. When the processor sets this bit to 1, it does not write a fault address to the BFAR. This is an asynchronous fault. Therefore, if it is detected when the priority of the current pr...

Graco Swing By Me - Battery to AC wall adapter modification

If you have one of these Graco battery powered swings you are probably familiar with the cost of C batteries! The swing takes four of them and they only last a handful of days. I'm not sure if the newer models support being plugged into the wall but ours didn't. If you are a little familiar with electronics and soldering, here is a rough guide on how you can modify yours to plug in! I wasn't sure how exactly to disassemble the swing side where the batteries were. I was able to open up the clamshell a bit but throughout this mod I was unable to determine how to fully separate the pieces. I suspect that there is some kind of a slip plate on the moving arm portion. The two parts of the plastic are assembled and the moving arm portion with the slip plate is slid onto the shaft. Because of the tension in that slip plate it doesn't want to back away, and because of the mechanicals that portion of the assembly doesn't appear accessible in order to free it. I was...
