R4

Alex board VDD tap cable doesn’t appear connected.
1. Boots with VDDD=1V and GPIOs are toggling.

2. Boots with VDDD=1V connected during programming (double boots when we kept VDDD connected). Once booted with VDDD connected and clocks calibrated, then we can remove VDDD and boot repeatedly.

3. UART I working

4. TX is working

R5

Did not boot with VDDD=1V but perhaps we could try different voltages in the future

R7

1. Boots when tapped with VDDD=1V

2. Boots with VDDD=1V connected during programming (double boots when we kept VDDD connected). Once booted with VDDD connected and clocks calibrated, then we can remove VDDD and boot repeatedly. After removing VDDD. VDDD_LDO output=0.962V

3. UART is working!

4. Radio? not working atm but probably we need to add the SMA antenna.

R13

didn’t work after 5 attempts

R14

didn’t work

R15

high leakage. 8-9mA of current draw. Likely connected VDDIO to VBAT/VDDD
1. Still boots with ALLGPIOToggle.bin

2. UART not really working. (garbled)

3. Radio looks like it’s transmitting but haven’t received packets. this board is hard to program overall

Q2

VBAT is not connected? get .047nA current

Q6

Cold boot working radio!
