Cortex-M3/M4 Debugging

Good post to change Imprecise abort to Precise by disabling buffering ((DISDEFWBUF bit in ACTLR register)
http://chmorgan.blogspot.in/2013/06/debugging-imprecise-bus-access-fault-on.html

In your OS, specially in Cortex-M3/M4 a good step would be disabling of nested interrupts by setting same interrupt priority level for all interrupts.

Bus fault (imprecise error) occurs in peak busy state, if number of bits for PRIORITY GROUP and PRIORITY LEVEL are not properly set in n4ixxxx.c.

CCS Project settings

New-> CCS Project -> Target = K2GEVM


VFP -> vfplib
Remove NEON
C:\X\INC
n4e7aal.lib
C:\X\LIB\ARM\CCS7
10063
10068
__RESET
"STACK=0x800FC000"
Unaligned access = off
enum_type = int

For debugger,

select new -> Target configuration -> Select Board Target Name. (Not CPu name, then only all the board configuration will be available). For example, AM437x Starter Kit, it will be SK_AM4374.
Then, use the device configuration in Debug window.

NIOS Quartus Prime GCC version

Quartus Prime Lite and Standard version seems to be stopped in 19.1. Only Quartus Pro seems to be released 19.2, 19.1 etc. For you, only the GCC version matters.

Reference design

Serial is tested with dev.

Max 10 reference design is taken from server. UART is not checked. May be there is no reference design that supports UART. -DUART is not used.
