I added the following function to convert an uint8_t array to uint32_t. But west build with warning: array subscript 'uint32_t {aka unsigned int}[0]' is partly outside array bounds of 'uint8_t[1]' {aka 'unsigned char[1]'} [-Warray-bounds]
574 | *regVal = spiData2Uint32(rxBufU8);
uint32_t spiData2Uint32(const uint8_t* pData) {
uint32_t data32[4];
for (int i=0; i<4; i++) {
data32[i] = *(pData + i);
}
const uint32_t ui = data32[3] << 16 |
data32[2] << 8 |
data32[1];
return ui;
}
