PSOC 6 Bootloader CE213903

[mrsinger]

I'm trying to bring up the CE213903 bootloader example on a CY8C6247FDI-D32.  The only changes I've made are to move the UART to P7 and change the baud rate to 9600.

When I run the bootloader host for APP1, I either get  'The key provided for the packet does not match the key that the bootloader expects.'  or 'Packet data invalid: the packet sent to the bootloader does not conform to the required packet format,'

If I leave the baud rate at the default 115200,  I get  'The bootloader reported error 'Packet length invalid: the packet's length does not conform to the required packet format'

Ideas or suggestions?

Hi @mrsinger ,

Please make sure you have given the same baud rate in the UART component in PSoC creator as well as Bootloader Host Tool.

Also please try and program the code following all the instructions in the readme file of the code example.

Please make sure you have not missed any steps mentioned in the document.

Regards,

Same baud rate.  I followed the instructions to the letter

There are two timeouts that assume 115000.  Intercharacter and packet.  Once I increased them for the lower baud rate the invalid packet failure went away
