MPC5777C Development Board/Kit

[berat24]

Hello everyone,

I would like to ask a question about MPC5777C development board.

When I examined MPC5777CEVBUG.pdf document, I saw that BOOTCFG pins have been connected to PC1 and PC6 pads respectively. However, I could not understand which pads have been connected to eSCI_0 RX and TX pins on development board.

Could you help me?

Btw, there is a photo below from my development board.

Sincerely.

Hi,

RXDA and TXDA pins of eSCI_0 (GPIO 89 and 90) are connected only to USB/UART transceiver FT232RQ. These signals are not available on pin headers.

If you want to have these signals on pin headers, use other GPIOs, there are more routing options. See System IO Definition xls file for details.

Regards,

Lukas

Hi,

I understood that I cannot use BAM module(serial bootloader) on development board because it does not have eSCI_0 Rx ve Tx connections to pads. Am I wrong?

Sincerely.

I can't see problem here - the USB-UART bridge should work with Rappid. It's standard converter which should be recognized as UART port in Rappid bootloader.
