UART Bootloader LPC55S16

Did I understand the table "Table 195. ISP pin assignments" correctly, that a bootloader which uses the UART interface is only usable with Flexcomm0 and i2c only with Flexcomm1? Or can I use UART also with Flexcomm1?

Hello @Ralf_Rademacher ,

The ISP boot is available on the following serial interfaces:

- UART0

- I2C1

- SPI3

- USB0_FS

- USB1-HS

So answering your question yes the USART ISP mode is only available on the FC0. Please let me know if you find this information useful.

Hi @nxf77486 ,

i think it wasnt the correct answer on what i initially ment. i think what i mean is a secondary bootloader. could it be, that i can use any FC i want for UART there?
