Binary Install Address for STM32WB5xxE(512K) and STM32WB5xxC(256K) devices.

Binary Install Address for STM32WB5xxE(512K) and STM32WB5xxC(256K) devices.

Hi!

In Release Note for STM32WB Copro Wireless Binaries writes what is install address for stm32wb5x_FUS_fw.bin depending on the chip model, as:

STM32WB5xxC(256K) - 0x0803E000

STM32WB5xxE(512K) - 0x0807E000

STM32WB5xxG(1M) - 0x080EC000

Is Ok, but for "stm32wb5x_BLE_Stack_fw.bin" one address specified:

stm32wb5x_BLE_Stack_fw.bin - 0x080CC000

This address is for 1M chip, but what is addresses for 256K and 512K chips ?

If use address 0x080CC000 = 835584 bytes but in 256K and 512K chips no such amount of flash memory.

Or am I not doing something?

Difference between  stm32wb5x_FUS_fw.bin and stm32wb5x_BLE_Stack_fw.bin for 1M chip is : 0xEC000-0xCC000 = 0x20000;

If it is a true, that to take address of stm32wb5x_FUS_fw.bin = 0x0803E000 for 256K chip, and subtract a 0x20000 = 0x1E000 - this is will an install address for stm32wb5x_BLE_Stack_fw.bin for 256K chip ?
