Hard fault (usage fault, invalid state), using X-CUBE-NFC03 and FreeRTOS, with STM32L4. Seems dependent on code/data size. Any idea where I should investigate ? Hello,I am trying to develop a FreeRTOS application which need to detect/read/write an NFC tag.I managed to make the NFC part work (based on ST's example code), but after changing my task stack size, a usage fault occurs (FORCED, INVSTATE).After a few attempt to reproduce and solve this, I noticed the following :Task size of 1024 words : work as expectedTask size of 768 : hard fault / INVSTATE in NFC library (see below)Task size of 2048 : hard fault / INVSTATE with PC out of any source file (0x20001fe8)ReturnCode ndefT4TPollerSelectFile(ndefContext *ctx, const uint8_t *fileId)
{
ReturnCode ret;
rfalIsoDepApduTxRxParam isoDepAPDU;
if( (ctx == NULL) || !ndefT4TisT4TDevice(&ctx->device) ) // HARD FAULT on this line
{
return ERR_PARAM;
}
ndefT4TInitializeIsoDepTxRxParam(ctx, &isoDepAPDU);
if (ctx->subCtx.t4t.mv1Flag)
{
(void)rfalT4TPollerComposeSelectFileV1Mapping(isoDepAPDU.txBuf, fileId, (uint8_t)sizeof(fileId), &isoDepAPDU.txBufLen);
}
