This document provides an introduction to OMAP4 pad configuration. It describes how to configure pads through 32-bit pad configuration registers for different power domains and functions. These include selecting pad modes, pull settings, input/output control, off mode values, and wake up detection. It also discusses power optimization techniques and provides examples of pad configuration code for the Linux kernel and a case study of pad configuration for the Talos7 board.

Learn bare metal driver development systems using Embedded C: Writing drivers for STM32 GPIO,I2C,SPI,USART from scratch
Software/Hardware used:
In this course, the code is developed such a way that, It can be ported to any MCU you have at your hand.
If you need any help in porting these codes to different MCUs you can always reach out to me!
The course is strictly not bound to any 1 type of MCU. So, if you already have any Development board which runs with ARM-Cortex M3/M4 processor,
then I recommend you to continue using it.
But if you don’t have any Development board, then check out the below Development boards.
Digital Weighing Transmitter with RS232/485 and analogue outputGeneral Measure
GM7702, a digital weighing transmitter with the standard dimension, is suitable for mounting on DIN rail in many industrial fields. Small size and flat compact design make it ideally integrate with whole weighing sector. Due to its high practicability, stability and easy operation, GM7702 can be widely applied to the industry of feeds, chemical, concrete and bitumen mixing, metallurgy smelting, etc..

netfilter is a framework provided by the Linux kernel that allows various networking-related operations to be implemented in the form of customized handlers.
iptables is a user-space application program that allows a system administrator to configure the tables provided by the Linux kernel firewall (implemented as different netfilter modules) and the chains and rules it stores.
Many systems use iptables/netfilter, Linux's native packet filtering/mangling framework since Linux 2.4, be it home routers or sophisticated cloud network stacks.
In this session, we will talk about the netfilter framework and its facilities, explain how basic filtering and mangling use-cases are implemented using iptables, and introduce some less common but powerful extensions of iptables.

3. Outline
● Overview
● Pad Configuration
● Off Mode Control
● Wake Up Detection
● Power Optimization
● Configuration How To
● Case Study - Talos7
4. Overview
● Configure pads to desired values according to device configuration
● Two sets of 32-bit pad configuration register
○ CORE power domain
○ WKUP power domain
● Each register has two pads with five fields functional bits
○ MUXMODE (3 bits)
○ PULL (2 bits)
○ INPUT ENABLE (1 bits)
○ OFF MODE VALUE (5 bits)
○ WAKE UP (2 bits)
9. Pad Configuration
● Off mode value
○ OFFMODEENABLE, off mode override control, 1 enable 0 disable
○ OFFMODEOUTENABLE, off mode output enable, 0 enable 1 disable
○ OFFMODEOUTVALUE, off mode output value
○ OFFMODEPULLUDENABLE, off mode pull up/down enable
○ OFFMODEPULLTYPESELECT, off mode pull type select
● Wake Up
○ WAKEUPENABLE, wake up detect enable
○ WAKEUPEVENT, wake up event status
13. Power Optimization
● Pin types
● Avoid unconnected or incorrectly pulled pins
○ For input, use pull up/down when possible
○ For output, avoid pull conflicts
○ For bi-direction, reconfigure the pin as an output driving 0
15. Pad Configuration
● Avoid unconnected pin (1)
○ If not driven externally, pull up/down is required
● Avoid pull conflict (2)
○ Prevent different pulls on the same line
● Avoid logic conflict (3)
○ if no external device drive the line, set the value as 0
○ else same value must
18. Configuration How To
● Boot-loader
struct pad_conf_entry {
u16 offset;
u16 val;
};
● Kernel
/* omap_mux_init_gpio - initialize a signal based on the GPIO number */
int omap_mux_init_gpio(int gpio, int val);
/* omap_mux_init_signal - initialize a signal based on the signal name */
int omap_mux_init_signal(const char *muxname, int val);
19. Configuration How To
● Kernel
/* Centralized control for pad init, suspend and shutdown */
struct omap_pad_state_description {
char *init_mux_name;
u16 init_config;
char *suspend_mux_name;
u16 suspend_config;
char *shutdown_mux_name;
u16 shutdown_config;
u8 flags;
