remove first dword: 10 00 7F 01
run IDA drag and drop bin file on ida window
select Processor type: ARM Little-endian [ARM], click Set, then OK

in next window setup memory map:

check "Create RAM section"
RAM start address: 0x1fff8000
RAM size: 0x18000
ROM
ROM start address: 0x4800
Loading address: 0x4800
Click OK

After load, click "Alt + G", change flag T to 1 (thumb mode)
now first dword is a stack pointer: in your case 0x20000000
second dword is entry point, go that (address-1) and press C (Code), or P (Procedure)
