Based on this hypothesis am335x EVM migration, according to the recently transplanted u-boot-2014.10 to tq335x. Not many places need to change.Because TI's am335x EVM developed using EEPROM to save configuration information on the ship. It uses different types of circuit boards to differentiate, and tq335x if there is no such eeprom. So. Need to change the EEPROM related parts, so that u-boot adapt to the t

A recent transplant of the lower u-boot-2014.10 to tq335x, if transplanted based on am335x EVM, does not require much change. Because TI's am335x EVM development uses an EEPROM to save the onboard configuration information, which distinguishes the different board models, and tq335x does not have the EEPROM, therefore, it is necessary to modify the EEPROM related parts, so that the u-boot adapt to the tq335x

Multitouch actually uses the multi-touch a protocol, but in the wrong place, this article based on Tq335x's rewritten touch drive is written according to the multi-touch B protocol, using the Tslib test normally, at the end of the article.TN92 touch screen using the touch chip is GT811, below we analyze the touch screen driver writing.(1) View schematic diagramAs you can see from the touchscreen schematic, there are four pins connected to the GT811 board, namely SDA, SDL, int, and reset.

Study Notes of AM335x (TQ335x) -- Nand NIC Driver porting, am335xtq335x After the sound card driver was transplanted, I wanted to continue and transplant the NIC Driver. However, I did not expect that the kernel maintained by TI is too robust. porting the NIC Driver is as simple as porting the key driver. The same is true for the Nand driver, I will introduce Nand and nic in the same article. Before the introduction, I would like to express my feelin

0 Introduction EDMA is the TI custom enhanced DMA data transfer mode, which, after a simple understanding, essentially designs a very efficient mode for merging multiple DMA transmissions. 1 Introduction to the Protocol A simple introduction to the protocol can refer to http://blog.chinaunix.net/uid-28818752-id-3749701.html and http://blog.chinaunix.net/uid-24567872-id-3161827.html.
