SPI Module

SPI Class

spi = HardsploitSPI(speed, mode, hardsploit_api)

Parametter	Type	Range
speed	byte	Range 1-255 SPI clock = 150Mhz / (2*speed) tested from 3 to 255 (25Mhz to about 0.3Khz)
mode	integer	SPI mode 0,1,2,3
Hardsploit	Instance of HardsploitAPI

SPI Interact

This function allows you to send commands to the chip.

spi.spi_ineract(payload)

Parametter	Type	Range
payload	interger	Byte array want to send (Max size : 4000 bytes)

Return : Same lenght array with answer of the slave

Signal

Port 1 : CS -> A0 SPI_CLK -> A1 MOSI-> A2 MISO -> A3

It is not possible to communicate at more than 37.50 Mhz because we have a sort of filter due to capacitance and impedance of the header and length of wires. (You can try more if you want for the moment we garanted 25Mhz)

SPI Generic Dump

This function allows you to read the memory of the chip.

spi.spi_generic_dump(mode, speed, read_spi_command, stPythonart_address, stop_address, max_size)

Parametter	Type	Range
mode	integer	SPI mode 0, 1, 2, 3
speed	byte	Range 1-255 SPI clock = 150Mhz / (2*speed) tested from 3 to 255 (25Mhz to about 0.3Khz)
read_spi_command	integer	The read command (see datasheet but most of the time 0x03)
start_address	integer	Start address (included) less than sizeMax -1
stop_address	integer	Stop address (included) less than start address and less than sizeMax-1
max_size	integer	Max 2^32 about 4Giga in BYTE 8000 bytes = 8000*8 = 64000 bits = 64Kb memory in datasheet for example 25LC640

Signal

Port A : CS -> A0 SPI_CLK -> A1 MOSI -> A2 MISO -> A3

SPI Generic Import

This function imports data from a file into SPI memory.

spi.spi_generic_import(start_address, 
                           page_size, 
                           memory_size, 
                           data_file, 
                           write_spi_command, 
                           write_page_latency, 
                           enable_write_spi_command, 
                           clear_spi_command, 
                           clear_chip_time, 
                           is_flash)

Parametter	Type	Range
start_address	integer	Start address (included) less than sizeMax -1
data_file	string	Path of file
memory_size	integer	Max 2^32 about 4Giga in BYTE 8000 bytes = 8000*8 = 64000 bits = 64Kb memory in datasheet for example 25LC640
write_spi_commad	integer	The write command (see datasheet but most of the time 0x03)
write_page_latency	integer	Time to wait after write cycle (see datasheet)
clear_spi_command	integer	The bulk erase command only for flash (see datasheet)
clear_chip_time	integer	Time to wait after bulk erase (see datasheet)
is_flash	integer	True if a flash memory (bulk erase in this case)
