От JTAG к IJTAG: зачем понадобился новый стандарт аппаратного тестирования

Приветствую! На связи Антон Осетров, DFT-разработчик SoC в компании YADRO. В этой статье я хочу рассказать о вызовах в тестировании SoC, о том, как они изменялись со временем и как с этим связан переход от аппаратного интерфейса JTAG к IJTAG.

MIK32 Амур + PlatformIO: пошаговый гайд по настройке среды разработки на Windows

MIK32 Амур (К1948ВК018) — первый российский 32-битный микроконтроллер на ядре RISC-V от АО «Микрон». Для работы с ним разработчики предлагают связку VS Code + PlatformIO. Казалось бы, всё просто — но на практике сталкиваешься с множеством неочевидных шагов, которые нигде не собраны в одном месте. В этой статье я пошагово покажу, как развернуть полноценную среду разработки для MIK32 Амур на Windows.

Мультитул для инженера: волшебная коробочка с I2C/SPI/UART/JTAG за 1.000 рублей

Будучи творческим человеком и техногиком, я обожаю при первой возможности апгрейдить своё оборудование. Время от времени я мониторю маркетплейсы в поисках чего-то новенького и в этот раз я наткнулся на настоящий мультитул для Embedded-разработчика — контроллер I2C/SPI/UART/JTAG в одной коробочке и всё это всего за 1.000 рублей... Конечно я не смог пройти мимо этой штучки и в рамках сегодняшней статьи хочу рассказать что оно из себя представляет и как с ним работать. Жду вас под катом!

Grr. ok with openocd I can probe the NAND over jtag, and see the info....

> nand probe 0
NAND flash device 'NAND 256MiB 3.3V 8-bit (Hynix)' found

> nand info 0 0 1
#0: NAND 256MiB 3.3V 8-bit (Hynix) pagesize: 2048, buswidth: 8, erasesize: 131072
#0: 0x00000000 (128kB) erase state unknown (block condition unknown)
#1: 0x00020000 (128kB) erase state unknown (block condition unknown)

but I can't read/dump. ☹️
> nand dump 0 test.dump 0x20000 0x800

Not sure what could be wrong/need changing. 😡 This is driving me mad, although I'm not an openocd expert to know why the info would work but read not.

does anyone know of a small (like a #teensy, or #seeed #xiao) cortex-m7 board? i have a teensy 4.1, but the lack of #JTAG/#SWD and direct access to the flash make it very clunky to work with. and no i don't want to solder mod the teensy to get access to the debug pins...

boosts in direction of embedded/hw communities much welcome.

Прошивка К1921ВГ015 без IDE и JTAG программатора

Итак, передо мной лежала полностью собранная плата и время стремилось к вечеру. Руки чесались хотя бы помигать светодиодом, а руководство было вскользь прочитано уже несколько раз, но тут меня осенило - у меня нет подходящего программатора!

Does anyone know of an inexpensive ARM aarch64 SBC that has a dedicated JTAG port? That is, one that doesn't multiplex with the SD slot and stays enabled after normal boot (or can be easily kept enabled without uboot recompile)?

We are happy to announce the first stable release V1.0.0 of bmputil! This Black Magic Probe Utility simplifies the process of keeping your Black Magic Probe configured and up to date. The main new feature is the ability to automatically find and download the newest Black Magic Probe firmware. No need to find binaries any more! Massive thanks to @dragonmux for a big push to make this release a reality! #opensource #rust #embedded #jtag #swd #debugging #mcu #electronics https://github.com/blackmagic-debug/bmputil/releases/tag/v1.0.0

Second iteration is assembled! Definitely some more work to be done to sort out UCPD issues. I am still wrapping my head around the CC and CCDB pins. Some preliminary bodges show promise. I think we will be able to start working on the software with @dragonmux soon after the bmputil V1.0 and Black Magic Debug V2.0 release. :D (DISCLAIMER: this is a long term project, don't hold your breath. If you need a BMP get the V2.3) #electronics #debugging #jtag #swd #mcu #stm32
