Hello. I tried to flash MT25QL512 chip with rp pico serprog from this git https://github.com/kazigk/pico-serprog What is the problem? Same problem on xtw100 [log_pico_serprog_MT25QL512.txt](https://github.com/dword1511/stm32-vserprog/files/9438204/log_pico_serprog_MT25QL512.txt)

Hi, I am trying to install this on my stm32-bluepill via a CJMCU-FT232H, but I just get "failed to init device". I am new to this and I am not...

Hello -- thanks for a great project! I just wanted to note for other readers searching the issues that this worked *fine* on my M1 Mac running MacOS 12.2.1 just...

I ghink the issue is that different chips are used xtw100 has stm32f103 xtw2 has gd32f103 chip. I have a XTW100 and one XTW2. Unlocked both via SWD and flashed...

The REVELPROG IS from https://www.reveltronics.com/en/products/revelprog-is-serial-memory-programmer-usb is also based on an STM32. This firmware could be ported to it and possibly extended for more features. The PCB seems quite simple. :)...

花了10.8买了一个stm 的demo板 原理图: http://lzdz.f3322.net:81/serprog-stm32vcp/STM32F103C8T6最小系统原理图.pdf 照片: http://lzdz.f3322.net:81/serprog-stm32vcp/1.jpg http://lzdz.f3322.net:81/serprog-stm32vcp/2.jpg http://lzdz.f3322.net:81/serprog-stm32vcp/3.jpg 也不清楚这个stm32 F103C8T6的真假,反正我是看不出来。 1、编译使用: make BOARD=stm32-vserprog-v2 make BOARD=stm32-vserprog-v3 生成的固件简单测试都能读写,不知道那个更匹配我的的这个板 USB D+(PA12)因这个板上有3.3v的接线端子,所以我直接焊了一个1.5k的1/4瓦的电阻上去了。 2、led的问题,修改配置 boards/stm32-vserprog-v2.h / * org #define BOARD_RCC_LED RCC_GPIOA #define BOARD_PORT_LED GPIOA #define...

有人用STM32F103vct6 做了nand的编程器 https://github.com/bbogush/nand_programmer 我觉得两个项目合并起来难度应该不大(都用的是STM32F103系列的MCU),共用一个固件,这个项目将mcu升到STM32F103vct6,然后将代码移植下就好了。刷写spi 用flashrom程序,刷写nand 用nando的程序

非常不错,用10多元钱的stm32做了一个一次成功。 测试环境win7_x64+VirtualBox(ubuntu 18.04_64),使用USB xHCI模式。 为什么用xHCI 因为我测试过在其它项目中usb使用xHCI 模式比EHCI的通讯速度快不少。 测试芯片winbond 25Q32FVSIG (4MBye),下面的结果是多次测试取的平均值: 读:6.255秒 657KByte/s ,擦除 45.69s ,写50.10s 81.74KByte/s (以上测试用的20030331的固件). 1、在linux下的用的是flashrom1.2,自己静态编译的版本i386版本(我发现在ub 16.04下动态编译的版本在ub18.04下尽然不能用)就索性编译了一个i386的静态flashrom。下载地址: http://lzdz.f3322.net:81/serprog-stm32vcp/flashrom1.2_i386_static.tar.gz 同样stm32flash也编译了一个,下载地址: http://lzdz.f3322.net:81/serprog-stm32vcp/stm32flash_i386_static.tar.gz 2、windows 下也测试成功了,但是安装那个stm vcp费了点功夫,看了帖子 http://www.openedv.com/forum.php?mod=viewthread&tid=72803 才解决了stm vcp安装后驱动出现感叹号的问题。 下载地址: http://lzdz.f3322.net:81/serprog-stm32vcp/stm_vcp_usb缺少的文件.zip...

what value has c1 ?

enhancement

On old project page (https://github.com/dword1511/serprog-stm32vcp) it is said that "Support LPC / FWH flash via parallel programming. [WIP]" but that about stm32-vserprog? Does it support LPC/FWH at hte moment?
