Arduino for STM32

Was solved - check https://github.com/stm32duino/Arduino_C ... sions/1866

Hi,

I am working on a project using the STM32L082. And during the code execution I would like to monitor the available RAM memory.
Does anybody know if there is a standard function available to monitor the available memory (RAM)?

Thans a lot

Thanks. CubeProgrammer tells me rev Z // so should be all good.
However have not been able to get it running yet. Will update here once I made some progress

Do I understand correct that when the first value of bank2 is an SRAM address it is considered valid?
Right. In Cortex M architecture, a binary always starts by Stack Pointer address, which should be in RAM.
Thus 1st U32 value of your bank2 should correspond to Stack Pointer, and is considered ...

Hi ABOSTM,

Thanks for the information


Explanations of Bank2 mechanism is detailed in Reference Manual RM0376
paragraphe § 3.3.2 Dual-bank boot capability
So you need to take car of BOOT0 pin.


The BOOT0 pin I have grounded on my PCB. In the STM docs (par 3.3.2 you refer to or AN2606) it is ...

Hello,

I am looking for your sample code on how to use the dual bank mechanism on the STM3L082.
My goal is to download the new firmware
Write it into bank 2 (starting from 0x0801 8000) (use the HEX generated by platformIO
Bank1 always remains as it is (with original firmware)
BFB2 is set to ...

Thanks for the suggestion / going to test it tonight and share the results.

Was not able to solve it and decided to switch off (power down thru MCU) the sensor instead of using the detachInterrupt().
Still looking for the solution and detach the Interrupt.

Implemented the clearPendingInterrupt () (see below). It is going to sleep now but the interrupt is not detached (as in deepSleep the MCU wakes up from the sensor INT).

void sleepLight2(bool useIntFromSensor)
{
#ifdef DEBUG
Serial.print(F("sleepLight: Int on (1) or off (0): "));
Serial ...

Thanks for the feedback.

Clearing potential pending interrupt might be the cause. Will have a look at it.
For the 328p processor I cleared the INTs by setting the following (but of course obsoleted for the STM32):


// Atmega 328P (obsoleted)
// EIFR = bit (INTF0); // clear flag for interrupt 0 ...
