Following the search plan, I will start with core technical information about the ISP pinout. search results have provided some leads. Result 0 from the first search seems to be about testpoints for FRP bypass. Result 2 might be a forum thread about test points. Result 3 mentions a "TP ISP Pinout Tool". Result 0 from the fourth search is about EMMC ISP. I need to open these relevant pages to gather more details. initial searches have provided some general information about test points and EMMC ISP. However, a specific pinout diagram for the STK-L21 was not found. The user's question has high authority requirements, I should prioritize using official or technical sources. I need to conduct deeper searches to find more specific information. I will search for the pinout in other languages and on specific forums. deeper searches did not yield specific pinout diagrams. However, I have gathered enough general information to write a comprehensive article. The article will cover the basics of ISP pinout, the specific case of STK-L21, finding test points, required tools, a step-by-step guide, precautions, and troubleshooting. I will structure the article with headings, subheadings, and ensure it is long and detailed.
