VladTParticipant
Question: do you have a fluent Russian programmer? It’s hard for me to explain the subtleties in English …
VladTParticipantYou do not understand … I will prepare a draft of my project with instructions on what to take from it and what to do so that you can repeat the behavior …
VladTParticipantif I give you a draft of my project that behaves “wrong” – is that enough?
VladTParticipantDoes not work! The question remained unresolved… In that post, questions, not statements …
VladTParticipantAny news on my question?
VladTParticipantAny news on my question? wait? Or is your product only LEDs to blink on STM32?
VladTParticipantboth options work))) and debug and release …

VladTParticipantover the weekend I will try to make a demo (my cut-down project with CAN) to reproduce the error you have …
VladTParticipantOkay. In the first message, I did not have enough information (Now I can say that there is another similar project where I observe the same picture … the same CPU + LwIP + CAN … On the CAN bus I observe a three-fold frequency drop …
The initialization code CAN is where I experimentally selected a divider that allows you to work in debug mode … I selected the divider using an oscilloscope …
For some reason, the Keil compiler does not want to be used. I only use it for checking. Before the errors occurred, both projects were originally written in VisualGDB + CubeMX.
static void MX_CAN1_Init(void) { hcan1.Instance = CAN1; #ifdef DEBUG hcan1.Init.Prescaler = 8; #else hcan1.Init.Prescaler = 21; #endif hcan1.Init.Mode = CAN_MODE_NORMAL; hcan1.Init.SyncJumpWidth = CAN_SJW_1TQ; ......... }
VladTParticipantA short description of my project:
CPU = STM32F427
LAN + USB (VirtualCOM port) + 8UART
The device receives a packet from the network, exchanges data on ports and sends the received data to the LAN. Additionally, an exchange can be made via USB with the desired uart …
VladTParticipantThe fact is that the project is quite loaded with functionality. More than 10 streams on FreeRTOS. How does it affect it?
VladTParticipantPlease read the first post of the branch … The configuration release works … The debug does not work … What does the power have to do with it? There are no breakpoints … Now I made a special connection to the release as advised – nothing was broken in the work …. I compile this project in Keil and everything works fine … The problem with USB and the frequency drop occurs only in debug mode …
VladTParticipantwe renewed the license …
VladTParticipantI added an email to my profile … the first where is registered and the second is my personal
VladTParticipantat the moment the support period has ended … the manager has requested an invoice for an extension … waiting …
By the way, along the way, the question is – is there a discount on the extension? or is it like buying a new license? -
