Using PEEDI
3.8 Multiple core support
Figure 3.5: Multi Target connection
Extra license SW-MULTIPROG is required to allow you to program multiple targets using only
single PEEDI. SW-MULTIPROG is required only when using ‘flash multi‘ sub-commands. The
targets must be chained using the multiple core cable adapter available from Ronetix:
WARNING:
All targets must have equal power supply (10% tolerance is permissible). The
highest power supply is taken for reference for the PEEDI output schematic, so the
JTAG signals will have that value.
WARNING:
As short as possible cables should be used, because the equivalent cable length is
the sum of all cables. Even then, you may need to decrease the JTAG clock in the
target configuration file.
The JTAG_CHAIN parameter in the PLATFORM_CORTEX section must be correctly set and each
core must be described.
Example PLATFORM_CORTEX section describing four chained cores:
