Hello, After much research, I was able to find the reason why jtag was unable to operate the computer's native parallel port (address 0x378). When running jtag with sudo, the error stopped occurring. user> sudo jtag jtag> cable DLC5 parallel 0x378 Ref.: https://urjtag.sourceforge.io/book/_jtag_commands.html I found something about adding the user to the group that has access to the parallel port, I don't know if it works with the cable init option above: Steps to Access a Parallel Port Accessing...

Hello, I haven't confirmed yet, but it's possible that the pins have to be numbered with an offset of 512 (in the current version of Linux). Without an offset, an error is occurring in the jtag when trying to initialize the cable via gpio: jtag> cable gpio tdo=9 tdi=10 tck=11 tms=25 But using offset, no error occurs: cable gpio tdo=521 tdi=522 tck=523 tms=537 However, before initializing the jtag program, it is necessary to export the gpio pins: pi> echo 521 > /sys/class/gpio/export pi> echo 522...

Hello, Unlike the sh7750, the sh7269 responded to the detect command and I was able to create the files, drivers for pins and bus, but I have some doubts. 1- Pin CS4 is shared with pin A22. But when trying to initialize the bus (initbus sh7269), it is requesting pin CS4 (which I did not declare on purpose). How can I get around this? 2- The file /bus/sh7727.c has hexadecimal addresses. Do these reference the memory map? Where can I find them?

I couldn't make any more progress, I don't think it's actually possible to add this model.

Hello, I found a post about adding support for SH7709S (SH3) to the old JTAG (before UrJTAG), and I managed to get it working with UrJTAG together with an Altera USB Blaster interface. The post is in Japanese, but Google managed to translate it well (pdf attached). http://www.mizore.jp/hoso/jtag/jtagtool.html I need to access the flash memory of the SH7750S (SH4). I have already managed to access the memory of the SH7709S (SH3). I tried to create a driver file for the sh7750, but it seems that the...

I tried to buy an XH-3001 with STM8, but it also came with a completely different MCU, it has a soic 16 casing, with code B2R3HFH logo FMD, buying these boards inside a case is always a surprise.
