'h2 should be changed to 'h1. 'h2 loads the current configuration.

Also, shouldn't we use the following format instead of manually setting the address?
axi_write (AXI_PWMGEN + GetAddrs(REG_RSTN), SET_REG_RSTN_RESET(1));

The #100 delays can be removed in all these axi writes, as they do not affect the functionality and are not mandatory.
