Had a similar experience 28 yrs embedded many RTOS some linux/UNIX like DEVICE
DRIVERS preference
I struggled just getting a kernel to build even after being trained by TI
LInux -> to me access to lots of app code if thats what you need
the cost a ton of overhead and too many places to look when it doesn't work
loss of bare metal control and embracing the printf debug model
Been able to finally build uboot and kernel from scratch then I realized the
revolution was never coming
beyond handheld pc like devices Linux will never COMPLETELY replace bare metal
or an RTOS
SO i have the boards have seen only one emebedded med device using am35x and
linux/wifi drivers
Meanwhile
I'm back to using SMP VxWorks with 8 core POwerPC Serial Rapid IO, fibre
channel, And guesss what
yes printfs. only the BSP team gets a JTAG
ARM has not replaced all other processors and RTOS or barebone on a multitude
of DSP's and uC AND sOC is where all the jobs are I get called for are
It all sounded so good and what a noble cause Linux on a TI chip in every
American school and company (-:
Uhhhm all those H1Bs posting on LinkedIN "kindly revert to me my college
project on BeagleBone so I can take your job""
Looks like they are all now experts on a platform few use (-:
replacing us almost happened but It never happened and wont. There is a God

dont even start thinking how you can solve a subtask. just go
and get your component out of the internet. talking caipirinha
serving robots doing your laundry, just call for it. it will
never be a 100% solution. be happy if it works just good enough,
more or less. On the other hand, if you do it on your own, how
perfect would you think you would do it, after endless doing
your stuff ..... There is just nothing you can do on your own
against the 10.000 man years of productive work you buy with
your cellphone ;)

>Newbie/Noob Rule 5: I dont know how, but all the people out

you are doing, in the end it works. you dont know why, or for
how long, but it does. thanks and regards to all of you out
there contributing to this vast community. With the stuff you do
and how you do it, you would not have survived in any kind of
industrial working environment. On the other hand this so
professional industrial working environment is just loosing the
edge against you. And that feels great :D

In my long career I have had to work with about a dozen different OS's on many
different hardware platforms from PDP-11's, Burroughs TC500, Univac Mainframes,
IBM/Amdahl Mainframes, Sun/Fujitsu SPARC Enterprise servers and lots more,
often dealing with multiples of them at the same time as part of earning a
crust.
It's dangerous to approach a new OS or hardware platform with the
attitude that you know all about computers and they must all work
the same way or else they are in some way impenetrable.
Forty-five or more years ago it was appreciated that different OS's
and hardware was the norm so you had to approach each one
differently and there was no shock in dealing with anything new.
My advice as always is to recommend saying daily to yourself "I
don't know jack about Linux" and just get on with it.
Leave the baggage behind, it's a handicap.
Regards
Sid.
