24 which extracts useful information from it. The resulting trace output
32 Sandbox is a build of U-Boot that can run under Linux so it is a convenient
33 way of trying out tracing before you use it on your actual board. To do

131 		it doesn't have a proper trace buffer. On many boards
145 This is kept as a separate option so that it is easy to enable/disable
153 When you run U-Boot on your board it will collect trace data up to the

169 that it captures most of the board init process, missing only the

254 to transmit it to the host. Notably you can use tftput to send the data
262 a trace log to address 10000000 and sends it to a host machine using

308 2. Build U-Boot with tracing and run it. Note the difference in boot time
309 (it is common for tracing to add 10% to the time)
314 4. Take a look at that code and see if you can optimise it. Perhaps it is
