LDC1612EVM: firmware upgrade

Jakub Kwolek62

Part Number: LDC1612EVM

Hi,

I purchased a LDC1612EVM and uploaded the wrong firmware to it using the GUI 1.9.4. The wrong firmware I am referring to is HDC10x0_EVM_Firmware.txt.

I found appropriate file FDC2x14_LDC13xxRevB_LDC16xxRevB_EVM_Firmware.txt in the same location, but firmware upload can't succeed - it takes around 10 minutes but still finished - what can i do in this situation?

Regards,

Jakub

Hi Jakub,

We can use the MSP430 BSL mode to fix this - refer to e2e.ti.com/.../295036

Chris,
thanks for the answer.
Actually, I need some more guidance.
Firstly, I think I should connect R6 to C29, not R2, according to circuit diagram from SNOU135A
I tried following scenarios:
1. I connected R6 to C29 before USB plugging, then launched firmware upgrade from Sensing Solutions EVM GUI menu - it didn't work.
2. I launched firmware upgrade, then with connected R6 to C29 - it didn't work.
3. The same as in 2. but after some time, when upgrade was still in progress, I disconnected R6 from C29 - it didn't work.

Any other recommendations?

Regards,
Jakub

Ok, it works with MSP430 USB firmware upgrade example after entering into BSL mode.
Thanks!
