I have followed this link https://weekly-geekly.github.io/articles/419037/index.html to implement PPPos in STM32. I changed the modem to "data mode" and then started PPP Connection. The modem communicating but the status callback throws PPPERR_CONNEC...

I am working on IAP boot-loader where the user application store either in 2 sector in which update comes in other sector respect to the current sector. So I need to build user app memory independent but I don't know how to do it. Could someone help?

I am working on IAP in STM32F4. I received .bin file using uart and flash it in 0x08004000 address successfully and disable irq , set msp , set vector, deinit hal , reset the systick registers but the jump is not working , It just freeze there. Can a...

I also tried your experiment suggestion and yes the address are changing at some specific byte location example app build at 0x08020000 is having byte value of 0x02 at many places and app build at 0x08060000 is having byte value of 0x06 at the same p...

Yeah I tried address independent option in keil linker option but the start up program file show error when I compile.

Is there a way I do it in program itself without changing them manually in system_stm32f4xx.c file?

Thank you so much. Your first suggestion works after the recent modification. But still didn't figured out how optimization affects it so much. I did IAP in HAL and APPLICATION also in HAL. Now its working fine now.Problems may arise when going to bu...

sorry it works without optimization and i figured out the problem. The problem is with the application code. I use Blink program and on Delay function call it get struck. I removed it and put a for loop for delay. Now it works. But why delay didn't w...
