To: "barebox@lists.infradead.org" Hi, I was trying to figure out the state framework recently , and found out that till version 2017.04.0 it kinda works with the following lines in my dtb : ############################################################################# / { state: state { magic = <0x27031977>; compatible = "barebox,state"; backend-type = "dtb"; backend-storage-type = "direct"; backend-stridesize = <0x500>; backend = &mmc1, "partname:6"; bootchooser { system0 { boot { reg = <0x00 0x10>; type = "string"; default = "system0"; }; remaining_attempts { reg = <0x15 0x4>; type = "uint32"; default = <0x3>; }; priority { reg = <0x20 0x4>; type = "uint32"; default = <0x15>; }; }; system1 { boot { reg = <0x25 0x10>; type = "string"; default = "system1"; }; remaining_attempts { reg = <0x40 0x4>; type = "uint32"; default = <0x3>; }; priority { reg = <0x45 0x4>; type = "uint32"; default = <0x14>; }; }; }; }; }; ############################################################################# The problem was it just worked for the first boot , after that it goes through a boot loop and all the remaining_attempts become zero , and I see the following bizarre logs on the console : ############################################################################# state: set parameter bootchooser.last_chosen: Invalid argument unable to handle paging request at address 0x14040008 pc : [<9fe05314>] lr : [<9fe05363>] sp : 9ffefab8 ip : 0000000c fp : 9fe56ad5 r10: 9fea17c8 r9 : 9fe56f8a r8 : 9fe56f71 r7 : 9011852c r6 : 8fefef40 r5 : 14040000 r4 : edfe0dd0 r3 : 00000000 r2 : 00000004 r1 : 90119214 r0 : 8fefef40 Flags: nzCv IRQs off FIQs on Mode SVC_32 [<9fe05314>] (remove_free_block+0x10/0x3e) from [<9fe05363>] (block_remove+0x21/0x24) [<9fe05363>] (block_remove+0x21/0x24) from [<9fe05667>] (tlsf_free+0x37/0x62) [<9fe05667>] (tlsf_free+0x37/0x62) from [<9fe08875>] (state_save+0x5d/0x6c) [<9fe08875>] (state_save+0x5d/0x6c) from [<9fe09c6b>] (bootchooser_save+0x33/0xa0) [<9fe09c6b>] (bootchooser_save+0x33/0xa0) from [<9fe09e3b>] (bootchooser_get_target+0x5f/0x7c) [<9fe09e3b>] (bootchooser_get_target+0x5f/0x7c) from [<9fe09e7b>] (bootchooser_boot+0x23/0xbc) [<9fe09e7b>] (bootchooser_boot+0x23/0xbc) from [<9fe0ba33>] (boot_entry+0x37/0x60) [<9fe0ba33>] (boot_entry+0x37/0x60) from [<9fe36a1f>] (do_boot+0x137/0x160) [<9fe36a1f>] (do_boot+0x137/0x160) from [<9fe02f25>] (execute_command+0x21/0x48) [<9fe02f25>] (execute_command+0x21/0x48) from [<9fe076d3>] (run_list_real+0x5a3/0x604) [<9fe076d3>] (run_list_real+0x5a3/0x604) from [<9fe073c7>] (run_list_real+0x297/0x604) [<9fe073c7>] (run_list_real+0x297/0x604) from [<9fe07035>] (parse_stream_outer+0x105/0x15c) [<9fe07035>] (parse_stream_outer+0x105/0x15c) from [<9fe070f1>] (parse_string_outer+0x65/0xa4) [<9fe070f1>] (parse_string_outer+0x65/0xa4) from [<9fe07777>] (source_script+0x43/0x68) [<9fe07777>] (source_script+0x43/0x68) from [<9fe077c3>] (do_source+0x27/0x46) [<9fe077c3>] (do_source+0x27/0x46) from [<9fe02f25>] (execute_command+0x21/0x48) [<9fe02f25>] (execute_command+0x21/0x48) from [<9fe076d3>] (run_list_real+0x5a3/0x604) [<9fe076d3>] (run_list_real+0x5a3/0x604) from [<9fe07035>] (parse_stream_outer+0x105/0x15c) [<9fe07035>] (parse_stream_outer+0x105/0x15c) from [<9fe070f1>] (parse_string_outer+0x65/0xa4) [<9fe070f1>] (parse_string_outer+0x65/0xa4) from [<9fe078b5>] (run_command+0x21/0x30) [<9fe078b5>] (run_command+0x21/0x30) from [<9fe0094d>] (start_barebox+0x2d/0x94) [<9fe0094d>] (start_barebox+0x2d/0x94) from [<9fe51e3b>] (barebox_non_pbl_start+0xbb/0xf8) [<9fe51e3b>] (barebox_non_pbl_start+0xbb/0xf8) from [<9fe00005>] (__bare_init_start+0x1/0xc) [<9fe535fd>] (unwind_backtrace+0x1/0x58) from [<9fe00bbd>] (panic+0x1d/0x34) [<9fe00bbd>] (panic+0x1d/0x34) from [<9fe51c11>] (do_exception+0xd/0x10) [<9fe51c11>] (do_exception+0xd/0x10) from [<9fe51c71>] (do_data_abort+0x21/0x2c) [<9fe51c71>] (do_data_abort+0x21/0x2c) from [<9fe51714>] (do_abort_6+0x48/0x54) ############################################################################# Now with the last version (2017.05.0) I have another problem. This is what I see on the console while trying to boot : ############################################################################# state: Cannot resolve "backend" phandle state state.7: probe failed: Invalid argument ############################################################################# The question is, how should I declare the backend in the dts file and which one is the most stable version that supports my case? _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
