VCN1L Bootloader wiped/corrupted

(1/1)

KBridges:
Hi All,

Could anyone give me any ideas as to why the bootloader would disappear or corrupt on the VNC1L?

Thank you in advance.

Hello,

Why do you think the bootloader has disappeared or corrupted?

To enable the bootloader, the PROG# pin must be driven low and the VNC1L must then be reset by driving the RESET# pin low then high. Run mode can be enabled by driving the PROG# pin high and then resetting the VNC1L by driving the RESET# pin low then high.

Refer to ANVNC1L-01 Vinculum VNC1L Bootloader for more information.

The Vinculum Firmware User Manual also details programming options in section 3.1.3.

It would be worthwhile connecting a 3.3V TTL cable to the VNC1L and using FT_PROG to try and reprogram the VDAP firmware found here:

This is not a common issue that other community users could help with.
You might want to contact your local support team:

Hello,

The VDIP1 module becomes unresponsive and fails to illuminate the LEDs. Re-programming the VDAP software onto the VDIP1 module rectifies the issue.

I've emailed the support team and I've yet to receive a response.

Could it be an issue with the power supply to the module?

Kind regards,

Kristian
