How to program STM32L15x data eeprom

Anybody know what the correct settings are to program the data eeprom of an STM32L15x device using a ULink2? This is the 4k of memory at 0x080800000 that can be erased on a word-by-word basis by application code. I was using a an STM32 Discovery board and that programmed fine via the ST-Link, but my release hardware uses a JTAG port and I am getting verification errors from the bytes of the data EEPROM. I've created an extra Programming Algorithm of "STM32L15x Low power Flash" in the Target Driver Setup and set the address and size but it doesn't seem to be able to program the data EEPROM. In fact it can program the binary '1's but not the '0's so I guess that the programming is working but the erasing is not?

Cheers,

This is now supported in MDK-ARM V4.50.
