ChibiOS Free Embedded RTOS

Nevermind, after investigating more I found that it was caused by another library that we use on top of LWIP.

Thanks for your quick reply.

The current trunk seems to solve this particular problem, although it brings a new one: LWIP breaks on an assert as soon as a second TCP connection is made ( the very first one works flawlessly apparently the first connection appears to break sometimes when receiving ...

Hi

I was testing LWIP with ChibiOS (latest, 17.6.3) on a STM32F107 (Olimex STM32-P107 board, rev. B), and noticed that it didn't work quite well (couldn't ping the IP). After some random trials, I found that I needed to insert a delay right after the call to macStart (in lwipthread.c). After ...

As I said, I need the small sectors so I can't put the data at the end (16 KB sectors vs 128 KB sectors make a huge difference for me).

I added the MSP initial value and reset handler address -- the same values that ChibiOS uses -- at the beginning of sector 0 (at address 0x80000000), and ...

Ok. Thanks a lot for your help Giovanni

So flash sector 0 can never contain pure data? That's annoying.

You need to have a vectors table at address zero containing at least the reset address and the MSP initial value.

Sorry but I know very little about vectors table, how would I do that?

How do you make the STM32 start at that address?
I don't know

All I did was changing the flash start address in linker script and CORTEX_VTOR_INIT, as shown in my first post, and I thought it was enough. Are you saying that the very first thing to run has to be at address 0? In this case, how ...

I imagine you have some kind of bootloader
No I don't. I just need the 4 smallest (16KB) flash sectors to store data, and unfortunately those are located at the beginning, that's why I'd like to move my firmware to sector 4 and directly boot there.

So no, no other code is run before my firmware ...

Thanks for the very quick reply.

SCB->VTOR correctly contains 0x10000 after chSysInit().

Hi

After I moved my firmware to sector 4 of flash memory, ChibiOS stopped working.

I changed this in linker script:
flash : org = 0x08010000, len = 448k

And added this in chconf.h:
#define CORTEX_VTOR_INIT 0x00010000

I erased the whole device memory, just in case. Firmware gets ...
