2.识别nandflash

kangear注：此文描述了u-boot中的分区
开启调试
修改wyh2440.h
/*
*debug enable
*/
#define DEBUG
#define CONFIG_NAND_DEBUG
修改s3c2440_nand.c
+#if !defined(CONFIG_NAND_DEBUG)
+#undef debug
+#define debug(fmt,args...)
+#endif
+#define S3C2440_ADDR_NALE 0x08
+#define S3C2440_ADDR_NCLE 0x0c
修改 s3c2440_hwcontrol 函数
static void s3c2440_hwcontrol(struct mtd_info *mtd, int cmd, unsigned int ctrl)
{
struct nand_chip *chip = mtd->priv;
struct s3c2440_nand *nand = s3c2440_get_base_nand();
debug("hwcontrol(): 0x%02x 0x%02x\n", cmd, ctrl);
if (ctrl & NAND_CTRL_CHANGE) {
ulong IO_ADDR_W = (ulong)nand;
if (!(ctrl & NAND_CLE))
IO_ADDR_W |= S3C2440_ADDR_NCLE;
if (!(ctrl & NAND_ALE))
IO_ADDR_W |= S3C2440_ADDR_NALE;
if(cmd == NAND_CMD_NONE)
IO_ADDR_W = (ulong)&nand->nfdata;
chip->IO_ADDR_W = (void *)IO_ADDR_W;
/*
if (ctrl & NAND_NCE)
writel(readl(&nand->nfconf) & ~S3C2440_NFCONF_nFCE,
&nand->nfconf);
else
writel(readl(&nand->nfconf) | S3C2440_NFCONF_nFCE,
&nand->nfconf);
*/
}
if (cmd != NAND_CMD_NONE)
writeb(cmd, chip->IO_ADDR_W);
}
没完没了的hwcontrol() dev_ready打印信息
还是取消nand 的debug信息吧
/*#define CONFIG_NAND_DEBUG*/

Jun 18, 2023 am 09:08 AM
With the continuous development of artificial intelligence technology, face detection and recognition technology has become more and more widely used in daily life. Face detection and recognition technologies are widely used in various occasions, such as face access control systems, face payment systems, face search engines, etc. As a widely used programming language, Java can also implement face detection and recognition technology. This article will introduce how to use Java to implement face detection and recognition technology. 1. Face detection technology Face detection technology refers to the technology that detects faces in images or videos. in J
Win10 is recognizing the solution for being unable to connect to the internet
Jul 11, 2023 pm 06:21 PM
When you use a win10 computer, have you ever encountered a situation where you are unable to connect to the internet? If you don't know how to solve this problem, let's take a look at this article. 1. Use the Win+I key combination to bring up the settings window, click to select Network and Internet. 2. Click Ethernet on the left side of the Network and INTERNET window, and then click Change Adapter Options in the right window. 3. In the Network Connection window, right-click Ethernet (desktop, please treat mobile devices as appropriate), and click Disable in the menu. 4. After it is displayed as disabled, right-click the Ethernet mouse and execute the enable command. Once Ethernet is enabled, the problem should be resolved. Here is an introduction to Win10 network failure prompt identification without
An article talking about the traffic sign recognition system in autonomous driving
Apr 12, 2023 pm 12:34 PM
What is a traffic sign recognition system? The traffic sign recognition system of the car safety system, whose English translation is: Traffic Sign Recognition, or TSR for short, uses a front-facing camera combined with a mode to recognize common traffic signs (speed limit, parking, U-turn, etc.). This feature alerts the driver to traffic signs ahead so they can obey them. The TSR function improves safety by reducing the likelihood that drivers will disobey traffic laws such as stop signs and avoid illegal left turns or other unintentional traffic violations. These systems require flexible software platforms to enhance detection algorithms and adjust to traffic signs in different areas. Traffic sign recognition principle Traffic sign recognition is also called TS

Has facial recognition for pets been implemented?
Apr 13, 2023 pm 07:52 PM
Translator | Reviewed by Cui Hao | Sun Shujuan Technology that can accurately identify animals will help owners reunite with lost pets, farmers monitor their livestock, and researchers study wild animals. Based on the above application scenarios, microchips are the most popular pet identification method. However, implanting a chip requires invasive surgery, specialized equipment to read the chip, and the risk of a thief extracting the microchip. Another method is DNA analysis, which although accurate, is also very expensive and time-consuming. Today I want to introduce to you how to identify animals through facial recognition. 1. Pet facial recognition using computer vision software Pet facial recognition by computer vision solutions can be used as an alternative to the above solutions. Despite its shortcomings,
