STM32L series first write to EEPROM fails

I have an STM32L073CZ that I'm having an occasional error with. I'm using the HAL libraries to program EEPROM and a number of our MCUs are seeing errors where they fail to write the first word. After that it'll start working correctly and everything ...

On the STM32H (not L) I need to use a 1-wire EPROM, and I try the generic driver calls generated by the IDE (HAL_SWPMI_Receive, HAL_SWPMI_Transmit, HAL_SWPMI_MspInit, etc.) and I see no bits going out on the scope, and the transmit times out.

I can "Transmit" but the TXE flag never clears and the transmit times out. It's unclear which parts of the bus are fully automated (reset, discovery, etc.) and how much of the CRC is handled, etc. I can see nothing on a scope, but if the chip gets in...
