For those who have worked on PCBA automatic testing production lines, chip programming is certainly familiar. Typically, after soldering components onto a bare board, functional testing is conducted, which involves programming the chips on the board with existing test programs and then testing whether the input and output logic is normal. So how do we … Read more
Abstract Chip programming is an important part of the production process of electronic products, and the efficiency of programming is a key concern for customers. The efficiency of programming is closely related to the programming speed of the chip. What factors influence the programming speed of chips? 1. Different Manufacturers’ Chips The differences between chip … Read more
Today, let’s talk about what PCBA chip programming is? The importance of chip programming in PCBA processing. In the one-stop service of PCBA (Printed Circuit Board Assembly), chip programming is a crucial link. For purchasing personnel in electronic device manufacturers, understanding the meaning of chip programming and its role in the entire production process is … 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
The address-specified write function supports EMMC_AUTO_ISP (flying line programming), EMMC_AUTO (offline 8x programming), EMMC_AUTO_4BIT (offline socket 4x programming), and EMMC_AUTO_1BIT (offline socket 1x programming). The operation methods for several programming modes are the same, and we will take EMMC_AUTO as an example to introduce the “custom address writing” function. After selecting the EMMC_AUTO function, click … Read more
Introduction to JTAG JTAG (Joint Test Action Group) is an international standard testing protocol (IEEE 1149.1 compliant), primarily used for internal testing of chips. Most advanced devices today support the JTAG protocol, such as DSPs and FPGAs. The standard JTAG interface consists of 4 lines: TMS, TCK, TDI, and TDO, which correspond to mode selection, … Read more
