The STM32-E407 topic

[mabl]

I tried J-Link GDB. I do not know how to setup OpenOCD.

Hi Todor, I think I used this Config for my JLink EDU and the E407

Code: Select all

monitor endian little
#monitor speed 12000
monitor flash device = STM32F407VC
monitor flash breakpoints = 1
monitor flash download = 1

Code: Select all

tbreak main
monitor reset 0
continue

Thanks !

I got tired of Eclipse. Is there an IAR demo project for this ?

Best regards,
Todor

There is an IAR example project under ./demos/ARMCM4-STM32F407-DISCOVERY. It should be easily adapted, just copy the project files.

Thank you. I did it for couple of hours.

Hi, Giovanni
I did some tests with the lwip and fatfs together as a web server (files are read from the card and transmitted as web pages) but it looks extremely slow 1kB a second.
Do you have any idea why it is so slow ?

Best regards,
Todor

[Giovanni]

It depends, how data is read and written? in general small blocks hurt performance. Try to isolate the problem, first lwIP without FatFS then reversal.

Thank you Giovanni.

I will debug it. Btw, do you plan to do ChibiOS plugin for IAR so that I can trace the threads and the thread call stack?

Best regards,
Todor

[Giovanni]

Yes but it is not high-priority and cannot give a timeline.

Hi, Giovanni

I cannot figure out if the ETHERNET driver is using DMA or not? Do you know if it is with DMA if not do you plan to use it ?
Is there any samples of the usage of your DMA driver?

Best regards,
Todor
