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

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

Best regards,

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

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

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

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
