J-flash Keygen

When you need to go for mass production, it is common to employ a contract manufacturer (CM) to mass-produce products. CMs have access to the customer's IP and large quantities of the components they are contracted to produce. Because of this, it is essential that customers control both their IP and limit CM production to prevent theft and secure revenue. To combat these threats, Flasher Secure uses mutual authentication, authorization, and confidentiality to secure your IP and production run. As an IP owner, you have full end-to-end control of your production chain.

End-to-End Security

Flasher Secure supports vendor-specific trusted firmware features to ensure end-to-end encryption, authentication, and confidentiality covering the whole process including the 'last mile'.

Modern products carry a huge amount of intellectual property (IP). From the IP owners point of view most of the IP is located inside the firmware. IP owners want to protect their IP. The Flasher Secure system uses authentication algorithms to make sure, that only authorized boot loaders and firmware are used in the system. If one component is not genuine, the device will stop working. Simply copying the firmware and/or bootloader from one device to another is not possible any more.

A secure production programming system capable of deploying device signatures and other security tokens is a central part of a device management system, that provides security updates during the lifetime of a product without sacrificing IP protection. SEGGER's Secure Product Lifecycle Management system provides a concept of such device management system.

J-Flash SPI is a PC software running on Microsoft Windows (backward compatible down to Windows 2000) systems, Linux or macOS, which allows direct programming of SPI flashes via J-Link or Flasher. The flash is programmed directly via J-Link using the SPI protocol, no CPU / MCU in between.

  • Direct programming of SPI flash via J-Link (no CPU / MCU in between)
  • Since J-Link communicates directly with the flash, even flashes connected to CPUs not supported by J-Link can be programmed
  • Cross-platform (GUI and command line version available for Windows, Linux and macOS)
  • Auto-detection of popular SPI flashes
  • Any SPI flash can be supported. All flash parameters can be manually configured/overridden, if required
  • Can be controlled via command-line
  • Part of the J-Link software and documentation package

J-Flash SPI - programming tool for SPI flash memories that simply works!

J-Flash SPI is a PC software running on Microsoft Windows (backward compatible down to Windows 2000) systems, Linux or macOS, which allows direct programming of SPI flashes via J-Link or Flasher. The flash is programmed directly via J-Link using the SPI protocol, no CPU / MCU in between.

Most common SPI flashes are automatically recognized by their respective ID and can easily be programmed with no further setup / configuration of J-Flash SPI needed to be done by the user.

In order to use J-Flash SPI, either a higher-end J-Link model (J-Link PLUS or higher, click here for the debug probe model overview) or a Flasher Production Programmer (click here for the flash programmer model overview) is needed.

20-pin connection

The following table lists the pinout for the SPI interface on J-Link / Flasher.

PinSignalTypeDescription
1VTrefInputThis is the target reference voltage. It is used to check if the target has power, to create the logic-level reference for the input comparators and to control the output logic levels to the target. It is normally fed from Vdd of the target board and must not have a series resistor.
2Not connectedNCLeave open on target side.
3Not connectedNCLeave open on target side.
5DIOutputData-input of target SPI. Output of J-Link, used to transmit data to the target SPI.
7nCSOutputChip-select of target SPI (active LOW).
9CLKOutputSPI clock signal.
11Not connectedNCLeave open on target side.
13DOInputData-out of target SPI. Input of J-Link, used to receive data from the target SPI.
15nRESETOutputTarget CPU reset signal (active LOW). Typically connected to the reset pin of the target CPU, which is typically called 'nRST', 'nRESET' or 'RESET'.
17Not connectedNCLeave open on target side.
195V-SupplyOutputThis pin can be used to supply power to the target hardware. Older J-Links may not be able to supply power on this pin.

Pins 4, 6, 8, 10, 12 are GND pins connected to GND in J-Link. They should also be connected to GND in the target system.

*On later J-Link products like the J-Link ULTRA, these pins are reserved for firmware extension purposes. They can be left open or connected to GND.

Pinout SPI 20-pin

The following table lists the pinout for the quad SPI (QSPI) interface.

PinSignalTypeDescription
1VTrefInputThis is the target reference voltage. It is used to check if the target has power, to create the logic-level reference for the input comparators and to control the output logic levels to the target. It is normally fed from Vdd of the target board and must not have a series resistor.
2Not connectedNCLeave open on target side.
3IO1I/OBi-directional data I/O pin 1
5IO0/DII/OSingle:>7nCSOutputChip-select of target SPI (active LOW).
9CLKOutputSPI clock signal.
11IO2I/OBi-directional data I/O pin 2
13DOInputSingle:>15nRESETOutputTarget CPU reset signal (active LOW). Typically connected to the reset pin of the target CPU, which is typically called 'nRST', 'nRESET' or 'RESET'.
17IO3I/OBi-directional data I/O pin 3
195V-SupplyOutputThis pin can be used to supply power to the target hardware. Older J-Links may not be able to supply power on this pin.

J-Link 10-Pin Needle Adapter Connection

The following table lists the pinout for the SPI interface on J-Link / Flasher when using the J-Link 10-pin Needle Adapter (model 8.06.04).

PinSignalTypeDescription
1VTrefInputThis is the target reference voltage. It is used to check if the target has power, to create the logic-level reference for the input comparators and to control the output logic levels to the target. It is normally fed from Vdd of the target board and must not have a series resistor.
2nCSOutput Chip-select of target SPI (active LOW).
4CLKOutput SPI clock signal.
55V-SupplyOutput This pin can be used to supply power to the target hardware. Older J-Links may not be able to supply power on this pin.
6 DOInputData-out of target SPI. Input of J-Link, used to receive data from the target SPI.
7Not connectedNCLeave open on target side.
8DIOutput Data-input of target SPI. Output of J-Link, used to transmit data to the target SPI.
9Not connectedNCLeave open on target side.
10nRESETOutput Target CPU reset signal. Typically connected to the RESET pin of the target CPU, which is typically called 'nRST', 'nRESET' or 'RESET'.

Pin 3 is GND pin connected to GND in J-Link. It should also be connected to GND in the target system.

Notes regarding nRESET: If there is another device / peripheral that also controls the SPI flash (e.g. a CPU the flash is connected to), nRESET of J-Link should be connected to the reset of the target system or the reset pin of the CPU to make sure that J-Link can keep the CPU in reset while programming the SPI flash.

J-Flash SPI connection

J-Flash SPI is able to auto-detect common SPI flashes automatically, via their respective ID. Anyhow, since all flash parameters (size, commands etc.) can also be manually configured by the user, any SPI flash device can be supported. The list of flash devices that are supported by the flash auto-detection of J-Flash SPI can be found here:

Jflash

Atmel / Adesto DataFlash

Atmel DataFlash is not supported by J-Flash SPI as its instruction set and handling in general is significantly different from any other SPI flash. Moreover, its page/sector size is not a power of 2, making it incompatible to existing concepts.

Selecting the right (Q)SPI flash that fits the needs can be a difficult task. There are plenty of different flashes as well as vendors available and creating a hardware for each candidate is time consuming and costly.

To make evaluation of different (Q)SPI flashes a lot easier, we have created a (QSPI) evaluation board.

Command line version

A command line version of J-Flash SPI is available for Windows, Linux and macOS, too. The command line version is also part of the J-Link software and documentation package. Please note that the GUI version of J-Flash SPI can also be controlled from the command line.

Jflash Keygen

Due to the high performance and the efficient protocol of J-Link/Flasher, programming speeds up to the max. flash programming specified by the flash vendor, can be achieved.
