Invalid Initializer Error when initializing a pointer to a struct

Question

I'm writing code for a USB bootloader. When I compiled the code, I got 2 of the following error:

Invalid Initializer

The error referred to the following lines of code:

static volatile usb_internal_sram_t sr;         
static volatile usb_internal_sram_t usb_sram = &sr;

usb_control_t ctr;                  
static usb_control_t usb_ctrl = &ctr;

Before someone suggests malloc(), this is an embedded system. Dynamic memory allocation is not advised as it can slow down the system. Hence, that is why I attempted to initialize the struct pointers this way. I thought this method would be ok, but apparently not. Anyone have any ideas? Thank you in advance!

"Initializing a pointer"? Where is the pointer??? I don't see any pointers being declared in your code. Why are you trying to initialize a struct object with a pointer value? — AnT stands with Russia

You are missing the * token to declare your usb_sram and usb_ctrl objects as pointers.

Oh wow, I'm an idiot. I totally didn't notice I forgot the *.

Are you going to accept the answer? That would be the right thing to do.

static volatile usb_internal_sram_t sr;
static volatile usb_internal_sram_t usb_sram = &sr;

you probably meant

static volatile usb_internal_sram_t sr;
static volatile usb_internal_sram_t* usb_sram = &sr;
