ESP32 IDF STPM32/33 SPI Issue

by neudeep - 0

This post discusses ESP32 IDF STPM32/33 SPI Issue and its solution, There are lot of issues reported on GitHub and aurdinio forum. Well ESP32 is from Espressif Systems and is a popular IoT controller used in embedded systems. While COVID-19 had accelerated most of the touchless and wireless features in any sort of product, these controllers like ESP32, ESP8266 had proven their time to market. In our product, While using SPI of ESP32, We are using esp32 wroom32. In our Smart Meter IoT Application Software, we need to read the internal registers of STPM32/33. As ESP32 is interfaced with STPM32/33- a popular metering module - over SPI. For that purpose, we are using SPI protocol. STPM32/33 has SPI peripheral which

EmbSysRegView Alternative Plugin For Eclipse

by blog_1buq8n - 0

If you are looking for alternate option for EmbSysRegView (embedded system register view) plugin or wondering 'How to Add Register Details View in Eclipse" this post describes simple trick to it. The standard Eclipse registers view shows only the core registers, which is not enough in embedded system development. So, EmbSysRegView – is an open source solution for 8, 16 and 32 bit microcontroller to display special function registers (SFR) while debugging. EmbSysRegView is a good plugin which supports GCC toolchain including GDB with Eclipse for emebedded system development, but it is not maintained and lacks support for new controllers. One can always refer to previous post we have seen how to add register details view in Eclipse for

EmbSysRegView In Eclipse For SAME54 On Ubuntu

by blog_1buq8n - 1

After successfully able to debug using OpenOCD and Eclipse, Now it is time to explore more. To start with, lets install EmbSysRegView plugin, This plugin gives similar functionality to the 'I/O view' in Atmel Studio 7. It displays special functions registers (SFR), peripheral registers values and memory values. This needed in embedded system development. Installation Bad news is, You can not install the EmbSysRegView plugin from the eclipse marketplace since eclipse marketplace is referring to old sourceforge download URL. Installation from Marketplace fails: An error occurred while collecting items to be installed session context was:(profile=_Applications_Eclipse.app_Contents_Eclipse, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=). Artifact not found: http://embsysregview.sourceforge.net/update/plugins/org.eclipse.cdt.embsysregview_0.2.6.jar. The new link to download is from sourceforge latest download, But it does not download full files and this

Debugging in Eclipse Using OpenOCD on Ubuntu

by blog_1buq8n - 2

This is second part of ongoing tutorial on setting up GCC + Eclipse + OpenOCD environment for use with the SAME54 Xplained pro board on latest Ubuntu system. In order to be able to follow this blog entry you must already have the gcc-arm toolchain and openOCD configured When we talk about debugging it is important to know that the actual "debugger" or emulation hardware is "on chip" and is called the "on chip debug" (OCD) hardware. While there are other methods to debug your embedded code using DDD, Kgdb, & Gdb on Ubuntu in this post will see debugging using Eclipse. Prerequisite - Download and install the latest version of Eclipse (open-source integrated development environment). Compile and install openOCD

ARM Cortex-M4 HOWTO Debug Under Ubuntu

by blog_1buq8n - 0

With SAME54 board and using OpenOCD will debug the LED Flasher example. This post assumes that basic setup is ready using GNU-ARM Embedded Tool chain and OpenOCD. Basic gdb with OpenOCD To Begin with connect the SAME54 explained pro board and start the OpenOCD server using telnet telnet localhost 444>reset halt Then it is time for gdb to use GDB via openocd there are couple of options like, gdb, ddd, insight and kdgb. Will start with gbd $arm-none-eabi-gdb --eval-command="target remote localhost:3333" AtmelStart.elf This will start gdb with remote debugging and you can see following message Type "apropos word" to search for commands related to "word"… Reading symbols from AtmelStart.elf… Remote debugging using localhost:3333 main () at ../led_switcher_main.c:55 55
