Sitara AM335x Series Resource Collection As the customer base continues to grow, I find that more and more customers have a lot of consulting needs for resources, some are just getting started, and some have been playing for a while. So I'm going to open a main thread here, with independent topics on each floor, to summarize some of the more scattered useful resources, so that everyone can easily index. EtherCAT Slave Solution Demo Application User Guide[/url] EtherCAT Slave Solution Demo Application User Guide[/url] EtherCAT application is popular in China. AM335x/AMIC110/AM437x/AMIC120 can support EtherCAT slave application, so here we start from scratch, taking AM335x/AMIC110 as an example, and describe the process of how to use this solution on the AM series, hoping to help everyone. For the installation and compilation involved in this article, and the final demo building part, you can directly refer to the relevant user guide. 〉〉〉Click to view details Routine of using EDMA to access SPI on OMAPL138
