0x01 Basic Overview Fault injection is a side-channel attack technique that introduces a certain form of disturbance or invalid state into a system to alter its behavior. Typically, in embedded hardware and electronic devices, this disturbance can take various forms. Common methods of fault injection in electronic devices include: – Clock glitch injection (imposing erroneous … Read more
There are currently three methods to program STM32: JLink, ULink, and Serial Programming, using tools such as JLink, ULink, and USB to TTL cable. ULink Programming During the installation of MDK, there will be a prompt to install the driver, which is the ULink driver. If you choose ‘Yes’, you do not need to install … Read more
The fuse bit is a bit that can be read at a specific address to determine the state of the fuse. A value of 0 indicates that it has been blown, while a value of 1 indicates that it has not been blown. When a high level is applied to specific pins of a microcontroller … Read more
1. Introduction In the light show section of the 19th competition, Infineon recommended a brand new LED driver chip: TLD7002. The TLD7002 chip has the following features: Supports up to 16 constant current output channels. Each channel can individually adjust the duty cycle. Each channel can individually adjust the current. PWM frequency can be adjusted … Read more
Beijing Zhixin Technology is a long-established chip decryption company that can decrypt a wide range of chip models.After decryption, we can provide chip programming services and programming recommendations.Some customers have reported programming failures during mass production; is this an issue with the chip itself?Or is it a problem with the programmer?What other possibilities might there … Read more
IC programming refers to the process of writing software (also known as firmware) onto an IC. Generally, products from the manufacturer are not pre-programmed, but they usually contain some code (for example, some chips have a unique serial number, boot section, etc.). This process is a necessary step that is even more important than IC … Read more
As technology continues to converge, we need a more agile and flexible development platform to support the full lifecycle testing of ECUs. The stages of ECU lifecycle testing are listed from left to right, representing the transition from pure software testing to pure physical testing. The left side utilizes more model-based technologies, which provides higher … Read more
