Hi Steve, After a few sleepless nights :lol: , I finally managed to get the application working with interrupts :-) I created a virtual APP IVT, and now all the jumps are correct. My biggest problem was that the APP IVT isn’t located before the program code, but rather in the middle of it. I first h...

Hi Steve, Thank you very much for your reply. I suspect that the problem is that the IVT code is not being written into the relocated area. I am using the Bootloader library in MPLAB, which states that the IVT is automatically relocated to address 0x2200. When I program an application using the UBHA...

Hello Steve, Thank you very much for your reply. Unfortunately, I am still having problems with the interrupts. I didn’t notice it at first because, for testing, I only toggled a pin using a timer interrupt… which it did, but only because a reset was triggered every time. As it looks, I am still goi...

Good news :-) It is now working! I can now successfully flash an application created with Flowcode using the bootloader that was created with MPLAB. The key point was the changes in the linker script. Only the application code must be relocated: program (xr) : ORIGIN = 0x2000, LENGTH = 0x133EC The I...

Hello Martin, Thank you very much for your reply. That sounds interesting—I just played around with it a bit, but so far without success :-( I’ve dealt with bootloaders and Flowcode several times before and have always ended up giving up. I really want to get it working this time :-) I hope Ben can ...

Hello Ben, I have created a bootloader for my dsPIC33EP128GM604 using the Microchip IDE. It works, and I can flash an application that was also created with MPLAB using the UBHA tool over UART. My problem: How can I correctly compile a Flowcode application so that the addresses are shifted to the co...

Hi Ben,

You're right. I wasn't aware that every byte is acknowledged. Have now tried it with the slave and it works great. The timeout setting is not a problem. Thank you for your help and the great support!

Hi Ben,

thanks for your quick help.

Hi Flowcode team, I have problems with the LIN bus component. I use a PIC18F25K80. When I try to send a simple message as a LIN master, it looks like this (see screenshot). There seems to be quite a long break between the individual bytes (20ms). There are also problems if I only send the header to ...

Hello, I have a professional Flowcode license and work with flowcode in my company. I do a lot of pre-development projects in the automotive sector, such as showcars, etc. In the new projects, I almost only have to work with the new CAN FD BUS. Is there a way to program the new microcontrollers with...
