I know this is a dumb question, but I've googled it and can't get an explanation. What is the "debug" column in the MAP file?Also, it's alarmingly big... using Keil is there a setting I should use to compile without whatever is taking up that space? I don't see the typical debug/release config settings.Thanks for the help.==============================================================================     Code (inc. data) RO Data RW Data ZI Data Debug   206256 18706 599208 7644 443828 3533745 Grand Totals 206256 18706 599208 1628 443828 3533745 ELF Image Totals (compressed) 206256 18706 599208 1628 0 0 ROM Totals

On the storage device on the nucleo-h743zi i just bought is a file "MBED.HTM"the ARM page https://os.mbed.com/platforms/ST-Nucleo-H743ZI/ explains:WarningThis platform is not yet available on mbed on-line compiler. Please use mbed-cli commands in the meantime.The following mbed APIs are also not supported yet: CAN, ETHERNET, USBDEVICEand i found an old post on the arm forum with an answer from an ST employee:https://os.mbed.com/questions/79170/When-will-the-STM32-Nucleo-H743ZI-be-sup/"Hi,Work still in progress.Thanks for your patience...posted by bco stm 19 Sep 2018"Is only one employee working parttime on this ?

Hello everyone,I spent the whole day trying to run the software STM32 Cube monitor (version 1.0.3) on my computer.I have tested with a Linux Mint and a Debian distribution and with the version 11 and 12 of the Oracle Java JDK but the problem is the same.When I run the software I get the message Error: Could not find or load main class com.st.mtt.guipower.MainAppCaused by: java.lang.NoClassDefFoundError: javafx/application/ApplicationI use the same command of the shortcut to run itjava -jar STM32CubeMonitor-Power.jarDoes anyone know what's the problem? Or if it's possible to download a previous version of the Monitor to test?Thank you very much for your help.

I am really confused that is it necessary or not. Because if I am going to the series STM32F030 these controller doesn't have in built EEPROM memory.

HiI am using the ​NFC5 V1.3.0 for the STM32L053R8-Nucleo as an example to port the RFAL library for using with either a STM32F051 or STM32G071. I replaced the Systick/NVIC/EXTI/GPIO/SPI Hal and everything seems to work, except that when I want to read out the UID of the used tag NFCV-15693 only 5 Bytes are read from the FIFO. On the Nucleo-Board the detection works fine. Do you have any idea where my problem is?Attached is the SPI communication with the not working MCU.Thanks in advance.Best regardsPatrick

Hi, I have two types of MCUs that I am building a board with. One is labeled as STM32WB55, while the other one is ES32WB55. Is there any difference between the two? I could not find any information on the ES32 chip in my Googling. I am having trouble connecting to the chip using an ST-Link. Does it have anything to do with the fact that I am using an ES chip? Thanks.

The problem was seen with STM32F303RD and STM32Cube_FW_F3_V1.10.0, but there is a possibility that other parts might be affected.When using USBD_CDC_SetTxBuffer followed by USBD_CDC_TransmitPacket with a packet of 64, 128, 192, etc. bytes, the data are not sent unless they are followed by another call to those functions with data length different than multiple of 64 bytes.A fix in the HAL library in explained in the thread below:https://community.st.com/s/question/0D50X00009XkXmgSAF/usb-cdc-breaks-on-heavy-loadThe fix is in PCD_EP_ISR_Handler function of the stm32f3xx_hal_pcd.c file. In one of the last lines of the function:if (ep->xfer_len == 0U)To be replaced by:if ((ep->xfer_len == 0U) && (ep->xfer_count < ep->maxpacket))The last lines of the function code would look like: /*multi-packet on the NON control IN endpoint*/ ep->xfer_count = PCD_GET_EP_TX_CNT(hpcd->Instance, ep->num); ep->xfer_buff+=ep->xfer_count; /* Zero Length Packet? */ if

Hi ,I am trying to interface a touch scren lcd with stm32 board. I have an mcufriend 2.4" touch screen lcd and i intend to interface it with nucleo-f303re board. I ,unfortunately, am not able to find a datasheet for the lcd. I know that the lcd can be interfaced with spi. but as i mentioned i do not have any datasheet for the lcd. Does anyone has any information on where to find the datasheet or a library for the lcd?

Hello,as the title suggest, I can't get printf() to work.I implemented _write() in my main() but during debugging the program never get there.The project was created with CubeIDE.int _write(int file, char *data, int len) { if ((file != STDOUT_FILENO) && (file != STDERR_FILENO)) { errno = EBADF; return -1; }   // arbitrary timeout 1000 HAL_StatusTypeDef status = HAL_UART_Transmit(&huart1, (uint8_t*)data, len, 1000);   // return # of bytes written - as best we can tell return (status == HAL_OK ? len : 0); }I know the hardware works, because the same implementation of _write() works in an other project (the one provided here).I am probably missing some compiler setting but I can't for the life of mine figure out what it is.Can someone please point me in the right direction?Best regards.Christoph

In the reference manual under 39.6.18 there is the description of the TAMP backup registers (TAMP_BKPxR).Neither in the RM nor in the STM32CubeL5 Hal I can find the base address of those registers.How can I read&write to TAMP_BKP0R - TAMP_BKP31R?

Hello All,I am currently working on a USB device that supplies power (Chip = STM32F765). I am attempting to have this device be connected and unrecognized while in stop or standby mode and I am running into the unfortunate fact that the DP line has an embedded pullup resistor on it. Even when I configure it as a GPIO input with a pulldown, the pull up and pulldown divide the voltage and it ends up remaining relatively high, which means that the pullup is physically before the alternate function mux when coming into the pin from outside of the chip. Having the DP line always high makes re-enumerating as a device when coming out of stop and standby mode difficult, because the connected host does not recognize that a new device has been connected. It already tried and failed to enumerate the device while it was asleep (because it sees the pullup when the device is asleep), so it doesn't retry enumeration when it wakes. If I could have it fall asleep with no pull-up, that would be ideal. T

Is it possible to assign the text alignment (left, center, right) through code? If yes, how?

Platform: STM32WB55 discovery board connected to I2S codec.My mission: To receive data from the codec using DMA transfer.Calling to HAL_SAI_Receive function returns the data correctly so I guess that everything is configured correctly.When calling to HAL_SAI_Receive_DMA, hdma->Instance->CNDTR stays on the same initial value.When debugging the code and running the HAL functions in single step - I do get the half full interrupt and the buffer contains the correct values. So again - I guess that everything is configured correctly.The base code is generated with CubeMX.HAL_SAI_Receive_DMA is called from the main loop, so I guess it is not related to interrupt priority issues.Any other ideas?Thanks!

The idea is to stack 3 X-NUCLEO-NFC04A1 on top of a NUCLEO-L476RG and access one X-NUCLEO-NFC04A1 at a time either from RF or through I2C using the X-CUBE-NFC4 or directly through HAL APIs.We were thinking of disable RF of two X-NUCLEO-NFC04A1 and enable for one at a time but when we are calling the API NFC04A1_NFCTAG_SetRFDisable() it is disabling RF of all the boards as all are stacked together that means hanging on the same I2C bus.Please help us to find a solution as we are now evaluating the ST25DV product for using it in one of our upcoming device.

Even though I did set optimization to "Disable for Debugging (-no)" there are certen lines of code which are removed by the compiler and are not available for setting a breakpoint and they do not get executed. This can be observed by certin results as well as by the disassembly missing mentioned lines. Is there a way to really disable optimization (including code removal) or at least a list of things that do get optimized even though -no ist used?

Posted on August 14, 2017 at 18:04Hello, I use STM8AF52xx, STVD and cosmic FSE, when I try to use  STM8S_StdPeriph_Lib and CAN example I encounter this error:&sharperror clnk Debug\stm8af52ax.lkf:1 @svlreg missing for function f_CAN_RX_IRQHandler(I have deleted LCD and LED functions just to have pure CAN because there was similar error concerning LCD/LED).This is part of code that is responsible for error:it is can_recieve() routineAs it seems error is caused by uint32_t variables, more precisely with data manipulations.I was able to assign pure numerical value, but combined statement (assign value from other variable and for example shifting left ) throws error.I can compile stm8s_can.c without problem, but if try to I build whole project I got error as stated at beginning.If I comment code with uint32_t variables project would build without errors.Workspace is available in attachment. What is causing this error?best regards,Radim.##error-clnk-@svlreg-mis

Hi,I'm trying to generate a new project for the STM32F469IDISCOVERY using CubeMX 5.2.0 and TouchGFX 4.10.0. All peripherals are initialized with the default modes. I use STM32CubeIDE as toolchain/IDE.After enabling the Graphics framework using TouchGFX in 'middleware', I press the 'generate code' button and code is generated. After that I press 'execute' to execute the TouchGFX GUI. Right after TouchGFX is started, I get the following error code: 'Error during code generation'.The following errors can be observed from the log: C:/TouchGFX/4.10.0/env/MinGW/msys/1.0/Ruby193/lib/ruby/gems/1.9.1/gems/touchgfx-cli-4.10.0/lib/touchgfx/generators/sw4_project_updater.rb:74:in `block in ensure_source_nodes': undefined method `add_child' for nil:NilClass (NoMethodError)   from C:/TouchGFX/4.10.0/env/MinGW/msys/1.0/Ruby193/lib/ruby/gems/1.9.1/gems/touchgfx-cli-4.10.0/lib/touchgfx/generators/sw4_project_updater.rb:62:in `each'   from C:/TouchGFX/4.10.0/env/MinGW/msys/
