| 1 The following target utilities or code components are currently buildable in | |
| 2 this target-utils tree: | |
| 3 | |
| 4 compalstage For Compal phones only: a little piece of code that is fed to | |
| 5 the original fw's bootloader via the serial download protocol | |
| 6 provided by the latter; it re-enables the Calypso chip boot ROM | |
| 7 and jumps to it, allowing our loadagent to be loaded in the | |
| 8 same way as on freedom-enabled devices. | |
| 9 | |
| 10 helloapp Template/skeleton for building programs like loadagent and | |
| 11 pirexplore. | |
| 12 | |
| 13 loadagent Loadagent is built to be loaded and run out of the Calypso | |
| 14 internal (on-chip) RAM, and does not depend on any hardware | |
| 15 outside of the Calypso chip itself - thus it should run | |
| 16 unchanged on all Calypso targets. It expects to be loaded by | |
| 17 the Calypso ROM bootloader in the UART download mode, and it | |
| 18 reads a RAM variable left behind by the ROM code that indicates | |
| 19 which UART has been used to perform that download - it then | |
| 20 uses that same UART to communicate with the host, presenting an | |
| 21 interactive command prompt. You can run loadagent "raw" by | |
| 22 loading loadagent.srec with fc-iram, but normally it is used | |
| 23 "behind the scenes" by fc-loadtool and fc-xram. | |
| 24 | |
| 25 pirexplore For Pirelli DP-L10 target only: this program is built in the | |
| 26 same manner as loadagent (also runs out of IRAM, expects to be | |
| 27 loaded with fc-iram, and presents an interactive command prompt | |
| 28 on the autodetected UART), but it automatically performs some | |
| 29 hardware (board level) initialization specific to the Pirelli, | |
| 30 and offers additional commands for exploring the hardware | |
| 31 features of this device. | |
| 32 | |
| 33 tf-breakin Here we build the payload for the tfc139 hack-utility; see | |
| 34 ../rvinterf/lowlevel/tfc139.c for the ugly details. |
