Writing With Flash Programmer; Programming Environment - NEC V850ES/SA2 UPD703201 Manual

18.2 Writing with Flash Programmer

Writing can be performed either on-board or off-board with the dedicated flash programmer.
(1) On-board programming
The contents of the flash memory are rewritten after the V850ES/SA2 or V850ES/SA3 is mounted on the
target system. Mount connectors, etc., on the target system to connect the dedicated flash programmer.
(2) Off-board programming
Writing to flash memory is performed by a dedicated program adapter (FA Series), etc., before mounting the
V850ES/SA2 or V850ES/SA3 on the target system.
Remark FA Series is a product of Naito Densei Machida Mfg. Co., Ltd.

18.3 Programming Environment

The following shows the environment required for writing programs to the flash memory of V850ES/SA2 and
V850ES/SA3.
Figure 18-1. Environment Required for Writing Programs to Flash Memory
Host machine
A host machine is required for controlling the dedicated flash programmer.
UART0 or CSI0 is used for the interface between the dedicated flash programmer and the V850ES/SA2 or
V850ES/SA3 to perform writing, erasing, etc. A dedicated program adapter (FA Series) required for off-board writing.
