In this webinar, we will show how to analyze a PAGE structure manually and then how to find a proper BCH codeword for an unsupported device. Timestamps are below.
Typical page structures for different controllers will be reviewed. BCH codeword structure, PARITY, and PAYLOAD areas will be explained. Then we will show how to detect the codeword parameters manually and automatically. In case of questions, please leave them in the comments.
