So some devices are exhibiting failure on both ROM programming as well
as RAM load with messages:

ROM Download Step 34 failed at position 136 bytes
Firmware Download Step 2 failed at position 8 bytes with (-110)

So I am going to revert to older delay values! With those we dont get a
failures. yeah looks like ROM load takes a while on these

Thanks
