From 4b48e6d46d7b5cf8758001aded9e74b1eca42c7d Mon Sep 17 00:00:00 2001 From: Jozef Lawrynowicz Date: Mon, 3 Aug 2020 19:58:33 +0100 Subject: [PATCH] MSP430: sim: Increase main memory region size The area between 0xFF00 and 0xFFC0 is unallocated in the simulator memory map, so extend the main memory region up to 0xFFC0 to allow the simulator to make use of the extra 192 bytes of space. sim/msp430/ChangeLog: * msp430-sim.c (sim_open): Increase the size of the main memory region to 0xFAC0. --- sim/msp430/ChangeLog | 5 +++++ sim/msp430/msp430-sim.c | 2 +- 2 files changed, 6 insertions(+), 1 deletion(-) diff --git a/sim/msp430/ChangeLog b/sim/msp430/ChangeLog index 41da2a734bd..345c804306b 100644 --- a/sim/msp430/ChangeLog +++ b/sim/msp430/ChangeLog @@ -1,3 +1,8 @@ +2020-08-07 Jozef Lawrynowicz + + * msp430-sim.c (sim_open): Increase the size of the main memory region + to 0xFAC0. + 2020-08-05 Jozef Lawrynowicz * msp430-sim.c (put_op): For unsigned multiplication, explicitly cast diff --git a/sim/msp430/msp430-sim.c b/sim/msp430/msp430-sim.c index a330c6caf5d..7be32cb62e9 100644 --- a/sim/msp430/msp430-sim.c +++ b/sim/msp430/msp430-sim.c @@ -138,7 +138,7 @@ sim_open (SIM_OPEN_KIND kind, if (sim_core_read_buffer (sd, MSP430_CPU (sd), read_map, &c, 0x2, 1) == 0) sim_do_commandf (sd, "memory-region 0,0x20"); /* Needed by the GDB testsuite. */ if (sim_core_read_buffer (sd, MSP430_CPU (sd), read_map, &c, 0x500, 1) == 0) - sim_do_commandf (sd, "memory-region 0x500,0xfa00"); /* RAM and/or ROM */ + sim_do_commandf (sd, "memory-region 0x500,0xfac0"); /* RAM and/or ROM */ if (sim_core_read_buffer (sd, MSP430_CPU (sd), read_map, &c, 0xfffe, 1) == 0) sim_do_commandf (sd, "memory-region 0xffc0,0x40"); /* VECTORS. */ if (sim_core_read_buffer (sd, MSP430_CPU (sd), read_map, &c, 0x10000, 1) == 0) -- 2.30.2
