SPI Programming Header
To program the boot code in to the SPI flash (for the first time or if boot code is corrupted), use iWave RZ/G1M/G1N
SPI Programmer Board through SPI Flash Programming Header (Example part: TMM-103-01-L-D).Optionally the
external SPI programmer can be used for programming the SPI flash through SPI Flash Programming Header (J1)
Optionally JTAG debugger through JTAG Header (J4). Optionally the external SPI programmer with 8pin SOIC test clips
(Example part: 923655-08 from 3M) can be used for programming the SPI Flash.
