This program is an example of the startup sequence for HackRF (Jellybean with
Lemondrop attached).
Test number of instruction per second (MIPS) slow blink ON 1s, OFF 1s
Then after 16s (the 16tests) it blink LED1/2/3 ON/OFF each 250ms.
This example compute the number of instructions per second executed called also MIPS (Millions of Instructions Per Second)
This example code run from SPIFI (SPI Quad mode) and the tests check different loop size to compute the cache size used with SPIFI and estimated to less than 256Bytes (about 128 instructions in best case and in Thumb2).
See result_exec_from_SPIFI.txt for more details.
Required Lemondrop -> Jellybean connections:
SCL: Lemondrop P7 pin 3 -> Jellybean P6 pin 3
SDA: Lemondrop P7 pin 5 -> Jellybean P6 pin 5
SDA: Lemondrop P7 pin 6 -> Jellybean P6 pin 6
VCC: Lemondrop P4 pin 2, 4, or 6 -> Jellybean P17 pin 2, 4, or 6
1V8: Lemondrop P11 pin 2, 4, or 6 -> Jellybean P16 pin 2, 4, or 6
GND: Lemondrop P5 -> Jellybean P13

Real speed expected from SPIFI without cache (with lot of nop)
Oscilloscope Freq SPIFI SCK = 22.50MHz to 22.83MHz (in reality 22.67MHz => 204/9 => SPIFI_CLK connected to IDIVB & IDIVB default=9)
So worst case 22.50Mbits*4 = 90Mbits/s => 11.25MBytes/s with an overhead of about 50% due to SPIFI protocol addr ... => 5.625MB
1 nop = 2 bytes (THUMB 0x00 0xBF) => Max 5.625 Millions instruction per second
110 NOP is in fact 110 + 9 (including loop overhead)
119*2 = 238 bytes
115NOP + 9 => does not enter in cache !! (248bytes)
Internal Cache size is about 256Bytes maybe shared Code/Data.
SPIFI obtained min=5.05 MIPS, max=195.6 MIPS
