https://www.quora.com/Which-is-the-most-comfortable-five-seater-hatchback-in-India

Factors to be available:
・Reclined rear seats for comfort, sleep and long travel
・More boot space
・larger windows and brighter (White, not black) cabin color
・High road clearance

Honda Jazz
・Check for reclined rear seats and Magic seat
・Seems to have flat floor surface

Further, the Jazz is the only hatchback in the market to get reclining rear seats, and also has a flat floor at the back (no hump due to the transmission tunnel). The rear seats also have the 'magic seats' trick, giving them a lot of flexibility.

I have taken test drive of Jazz, Baleno, Ford Figo, VW Polo, etc. I liked the Jazz the best. Only problem was I wanted automatic and top end Jazz (with magic seats) was not available with auto transmission. I went for Ford EcoSport instead. Baleno is quite good and VFM too but the rear seats are not comfy and have hard suspension, thus bumpy ride.

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.
