Hardware advice please
Hi, I have a current product that I am trying to move to ARM mbed. I have the following requirements and am having trouble finding hardware that works. I am asking for some suggestions. I need 1 I2C port 2 UART 1 SPI would like at least 2meg flash ( want to be able to implement a bootloader for remote software updates)
I have tried the following and every time I try I get a serial config conflict so I assume there isnt enough to support my needs and the basic needs to load and debug.
PSOC6 - cy8proto-062-BLE
Please help as I am at a loss. Even some advise on how to fix the serial conflicts would be fine.
Best Regards, Rob Berry

There should be solutions. The Nucleo L476RG has the peripherals you need, but has 1 MB Flash. The board page gives you info on the pins. For example:
D15 PB_8 I2C1_SCL
D14 PB_9 I2C1_SDA
D2 PA_10 Serial1_RX
D8 PA_9 Serial1_TX
D6 PB_10 Serial3_TX
You need to check the other boards in a similar way to find a solution. There may be issues with some boards. For example, the nucleos with Arduino pinout use Serial2 D0/D1 for communication with the Host PC. In case you really need 2MB you will have to go for something like the Nucleo-F429ZI
