ChibiOS Free Embedded RTOS

I know this thread is old, but I kinda got around it by restarting the i2c driver:

       i2cStop(cpuI2C);
       i2cStart(cpuI2C, &cpuI2cCfg);
       msg_t ret = i2cMasterTransmitTimeout(cpuI2C, addr, tx_buffer, 1,
                rx_buffer, 0, TIME_MS2I(10));

Hi,

I was complaining some time ago about H7 linker script
I have similar issue with F767ZIH. After loading the binary with the gdb:
(gdb) load
Loading section .vectors, size 0x200 lma 0x8000000
Loading section .xtors, size 0x8 lma 0x8000200
Loading section .text, size 0x89e8 lma ...

TWIMC: As a workaround, replacing flash1 with flash0 on each alias compiles and works ok (on ST-Nucleo-H743ZI)
$ svn diff

Using F7 linker scripts it will compile (at least).

So, I was comparing the linker scripts for H7 and F7 and I see that flash0 anf flash1 although point to the same thing (?) they have different addresses, but not for H7 (bank1+bank2 vs bank1).

flash0 : org = 0x08000000, len = 2M /* Flash ...

It seems that is coming from C++ stuff (commenting cpp out it will compile). I have nothing fancy/complex, just 2 classes.
On same configuration STM32F767 compiles just fine.

Latest version from dev.arm.com: GNU Arm Embedded Toolchain Version 7-2018-q2-update (7.3.1) and 6.3.1 from debian repo.

Since STM32H7 is M7 I didn't expected to have an compiler/linker problem...

I have a similar issue while trying to compile for STM32H743ZIT6
/usr/lib/gcc/arm-none-eabi/6.3.1/../../../arm-none-eabi/bin/ld: section .rodata VMA [0000000008008e90,0000000008009e77] overlaps section .text VMA [00000000080002c0 ...

Hi Giovanni,

$(CHIBIOS)/os/hal/ports/STM32/STM32F3xxHi,

My environment:
- ChibiOS version: m master branch, namely m
- Compiler: gcc version 6.3.1 20170620
- Platform and board: STM32F4xx, STM32F207 nucleo 144 board
- Nature of the problem: compiling EXTIv1

I started my project in May and today I updated to ...

I have same problem with F2 board (Nucleo-F207ZG) (ChibiOS - the current github master branch) and a BM085 sensor. Sometimes I receive a timeout.
Is this the recommended approach to recover from the locked state?
