02:09 <eZioPan[m]> hi, does probe-rs have some commandline interface to interact with target MCU’s memory and registers(like telnet interface of OpenOCD)?

02:12 <eZioPan[m]> VSCode is great, but if I just want to read a few bytes from MCU, then write down a config file, and start a debug session just be too heavy for me :)

04:13 <barafael[m]> You could do this using a USB-to-serial converter (also calls am 'ftdi'). This would require a free serial port on the device. The advantage would be that you would not be bound to a debugger, but your firmware would have to know how to receive serial commands. If you want to do it via debugger, then I would say reserve a page of memory for your config data and use sth. like

04:13 <barafael[m]> `probe-rs download 43439A0.bin --format bin --chip RP2040 --base-address 0x10100000`

04:15 <barafael[m]> `probe-rs download 43439A0.bin --format bin --chip RP2040 --base-address 0x10100000`

04:57 <eZioPan[m]> thanks! I might not make myself clearly, I want to halt the MCU, then read/modify some bytes from SRAM/peripheral register. I think I will need to use a debugger to access these bytes. Currently I try move from OpenOCD workflow to probe-rs one, thus I’d like to know a simple way with probe-rs.

05:05 <ithinuel[m]> You could use gdb's cli 🙂

05:05 <ithinuel[m]> Works well with cargo-embed.

05:05 <ithinuel[m]> You'd still need to create a toml config file to enable to gdb server... (full message at <https://catircservices.org/_matrix/media/v3/download/catircservices.org/FPooSjExcGYJIeXSOlSFLONR>)

05:05 <ithinuel[m]> * You'd still need to create a `.embed.toml` config file to enable to gdb server... (full message at <https://catircservices.org/_matrix/media/v3/download/catircservices.org/YKwBaECwQHrBLeLQhkQmSSIe>)

07:26 <burrbull[m]> `probe-rs gdb` should also work. Although I haven't try:... (full message at <https://catircservices.org/_matrix/media/v3/download/catircservices.org/JIMCfNxRbrGezRrVPbexEDgq>)

07:56 <eZioPan[m]> probe-rs gdb works

07:56 <eZioPan[m]> gonna pick up gdb command again ;)
