When I bought STM32WB35 chip, is there a binary in the radio cortex-M0+?

I watched the stm32WB workshop and studied the ble example on the stm32wb55 nucleo board and it worked well.

Now I'm trying to test the ble on my custom board, stm32wb35cc, but I didn't do anything.

The stm32wb manual found that the stm32wb35 contained cpu1 cortex-M4 and cpu2 cortex-M0.

Does it work if you put the binary related to the ble stack in Cortex-M0?

According to the "stm32wb getting started" document, there are binary (stm32wb3x_BLE_Stack_full_fw.bin) files, does it work by putting them in cpu2 cortex-m0?

If I buy a stm32wb35cc chip, is there no basic binary?

Never tested this configuration: stm32wb3x_BLE_Stack_full_fw.bin on the M0+ of a STM32WB55 device.

There are 2 directories stm32wb3x and stm32wb5x for each variant of the WB family. Using one for the other is not something I would play with but I don't think you will break your board here. It may simply not work.
