TWIM error crash , same code, two laptop

[Olfox]

Hi,

I moved my code on a second windows pc, checkout the code from git,download the same nordic sdk and softdevice version, same SES version but running on my board, the code crash after calling a twim transfert function :

I compared both project, there are similar, and it is running on my old laptop.

If fail on calling xfer function:

const nrfx_twim_xfer_desc_t my_xfer = {.type = NRFX_TWIM_XFER_TXRX,
.address=slaveAddr,
.primary_length = 2,
.secondary_length = (nMemAddressRead<<1),
.p_primary_buf = &addr,
.p_secondary_buf = data
};

err_code = nrfx_twim_xfer(&my_twi, &my_xfer ,0);

I have a guess that it could come from the environement but all software are installed at the same place in C:/ 

Do you have any clue may be ?

Thanks a lot for your help, i have no idea at the moment and after closing, cleaning rebuild etc the project i still don't understand.

Hi,

Looking at the printout, i.e. error coming from nrfx_twim.c:559, then it looks like you are hitting this assert at line 559.

So you should debug, and check if the lengths that you pass to this function is correct.

Hi Sigurd,

I noticed that I previously comment in the source file nrfx_twim this check   

NRFX_ASSERT(TWIM_LENGTH_VALIDATE(p_instance->drv_inst_idx,
p_xfer_desc->primary_length,
p_xfer_desc->secondary_length));

So my mistake... i don't know why there is this check but as i need to read in one shot 1700bytes, i disable this check ...

Thanks Sigurd :)
