MCSDK inverter

[iskan]

I'm using mcsdk and want to create an inverter file based on STM32G070CBTx, but when generating the project, it tells me that my selected hardware is not compatible with the algorithm

Hello @iskan ,

Could you please attach your board description. I will have a look on it and check what the issue is.

Regards

[iskan]

thank you very much indeed

Hello @iskan ,

Your issue is line 144. The actual name of the PC14 pin is "PC14-OSC32_IN (PC14)".

I modified this section as follow :

"OC_TRIGGER": [
{
"name": "PC14-OSC32_IN (PC14)",
"help": "CN10.14. Factory default. Solder R73",
"cost": 0
}
]

With this version updated, I was able to load your project, generate and compile the binary.

For your information, the genuine name is the one from the name section of the json description of the MCU.

In your case, you will find the following section line 1144 of the file STM32G071RBTx.json:

{

"name" : "PC14-OSC32_IN (PC14)",
"position" : "4",
"signals" : [ "GPIO_Analog", "GPIO_EXTI14", "GPIO_Input", "GPIO_Output", "RCC_OSC32_IN", "TIM1_BK2" ]
},

Cedric

Thank you very much. I would also like to ask why I couldn't find the inverter file when creating a project using G030C8Tx.

[cedric H]

Hi,

No obvious reason. G030 series is now supported from MCSDK 6.2.1.

If pins are aligned with pins name coming from mcu json file, then I propose you to attach your description in this thread, and I will check it.

Regards

Cedric

[iskan]

Yes, the version of mcsdk I'm using is 6.2.1, and the inverter file I'm using is the same as the one for the G071 mentioned above, except that I've changed the "mcu": "STM32G071RBTx" to "mcu": "STM32G030C8Tx", and I'm not sure if I'm going to have any problems doing that, so I'd like to ask you about it.
