No, that is not correct.

The final parameter of adl\_flhWrite is a u8\* pointer - it is the address of the start of the data to write.

Strictly, it would be more appropriate if this were a void\* pointer - see: [Garbage when reading flash - #8 by awneil](https://forum.sierrawireless.com/t/garbage-when-reading-flash/3612/8)
