Detailed issues to date 7/1/2024

  • 1.1.0:

    • Ethernet didn't work.

    • MS5601/BMP address conflict.

    • 2 layer..... caused some design decisions that could have been avoided.

    • Bodged around Effuse wrong calcs for rising edge trigger  - voltage from power mod was 3.26 instead of 3.3.

  • 1.2.0:

    • Ethernet still doesn't work - we changed 30 pin to same but with shroud so part in Altium changed, footprint looked same but was different so it was oriented incorrectly.

    • MS5611 wired up wrong - connected main I2c clock to wrong pin was a copy paste error.

    • Had DNP resistors but got populated (happened on 1.1.0 too) 3 bootstrapping for Wiznet and another for a sensor (R1). The issue was they were 0 ohm resistor so you had a short from power to gnd. 4

    • No Effuse problems.

    • I2c problems: too many transactions; bus will lock up. Same with 400 kHz will also lock up. thought it was because of LSM16

  • 1.2.1

    • Need to validate I2c issue.

    • TMP117: wasn't giving data just reporting zeros.

    • RS485 issue giving garbage. Aaron probed RS485 and got good data but probed after  transceiver (UART) and got garbage.

    • Ethernet works ( FINALLY)

    • A sensor module was reading garbage values (need to find and label)
