Hi Guys,I'm writting a bootlader/application for STM32L4 in STM32CubeIDE i I want my app to run even if there is no bootloader in memory. This is my *.ld file:/* Memories definition */
MEMORY
{
RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 96K
...
Hi Guys, I'm looking at STM32L475VET6 to use as OTG Host for USB Flash drive and usb barcode reader. Since USB hub is not supported by STM32L4 what is the best way to multiplex the D+/- pins of the MCU? I will always have the barcode reader connected...

Hello All,
I trying the following configuration of TIM4 on STM32L152
void Timer4Init(void) {
RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM4, ENABLE);
// Zero cross in - counter start CH3 ...
Posted on April 14, 2014 at 18:48Hi All,Can anyone please advise why there is no VBAT pin on STM32L152 MCU?I read that RTC runs as long as the MCU is powered...but when its not, then what ?How to implement RTC backup supply on this MCU?Thanks!regard...

Hello All,
I connected DAC1 output (S6 closed, S5 opened) to the internal OPAMP1 AIN+ which is in noninvering configuration by two external resistors (Rf=150k, Rg (to ground)=50k) which should yeld G=x4 ...
Hi PiranhaThe overlap is no the problem here, as everything goes into flash as expected as you could see. I understand how bootloader works but at dev stage in order to flash bootloader and app I'd have to manuallly merge bootloader hex and app hex ...
Thanks guys, I changed my bootloader func. to: SCB->VTOR=0x8001000;
asm("ldr R0,=0x8001004");
asm("BX R0");tried asm("ldr R0,=0x8001005"); too but same result.Of course I also did in system_stm32l4xx.c:#define VECT_TAB_OFFSET 0x1000This...
Hi Guys!I just Installed CubeMX 6.3.0 and X-CUBE-EEPRMA1 package but no EEPROM category is visible under Middleware Tree. How do I add eeprom fuctionality to my project?best regardsTomasz
Hi Pavel,Thanks for the tip, you are right Segger has a lib for this but for 4000Euro I would be glad to hack it myself :)I found TC7USB40FT USB multiplexer, it's cheap but I'm not sure how the enumeration will work while switching between slaves. I...
Posted on April 24, 2014 at 15:05Thanks Clive,So, as CH1 to CH3 as XORed I can still use TI1FP1 as trigger while the input signal is on TIMx_CH3 but I have to use input capture channel 1 ? RegardsTom
