ETERNA

™ SERIAL PROGRAMMER GUIDE

Accessing Eterna Flash

Once an appropriate device is established, the -r command can be used to obtain

additional information.

If an unlocked powered ETERNA is not present, the HSP_ERR_FLASHID error is

returned. If a locked ETERNA is present, the HSP_ERR_FLASHID error is returned for

all commands except the unlocking commands –u and –U. If an unlocking command is

attempted on an unlocked part, the HSP_ERR_FLASH_ID error is returned.

If the read is successful, all other valid ESP commands should function.

HSP_ERR_BADPARAM indicates a parameter out of range, such as an address outside

of 0x80000.

Erase Flash before Programming

When programming an image, the corresponding flash memory must have been

previously erased. Production LTC5800 parts are shipped by Linear with the flash

erased. Production LTP (PCB) parts are shipped by Linear with the flash images

loaded.

Other Common Issues

Other ESP errors are usually internal errors associated with the installation, which

includes: ESP.exe, FTCSPI.dll (HSP_ERR_LOADLIB), FTD2XX.dll, and the FTDI driver.
