hi qemu-devel,
i tried use the integrator.c to emulate the arm926 which has 128M message but found the RAM size can use is less than 32M. steps below. the qemu usding is 2.8. 1 define the RAM from 0-128M in ld file. 2 write the test program to verify i can write/read the memory from 32M to 64M continuously with address directly. 3 always failed when the size is close to 32M even though i changed start address. 4 error message: qemu: hardware error: integratorcm_write3: Unimplemented offset 0x0 CPU #0: R00=00000028 R01=00019000 R02=00000055 R03=10000000 R04=0000ea9c R05=00000505 R06=00000606 R07=00000707 R08=00000808 R09=00000909 R10=00001010 R11=0000feb4 R12=00000000 R13=0000fea8 R14=00000338 R15=00000300 PSR=20000153 --C- A svc32 s00=00000000 s01=00000000 d00=0000000000000000 s02=00000000 s03=00000000 d01=0000000000000000 s04=00000000 s05=00000000 d02=0000000000000000 s06=00000000 s07=00000000 d03=0000000000000000 s08=00000000 s09=00000000 d04=0000000000000000 s10=00000000 s11=00000000 d05=0000000000000000 s12=00000000 s13=00000000 d06=0000000000000000 s14=00000000 s15=00000000 d07=0000000000000000 s16=00000000 s17=00000000 d08=0000000000000000 s18=00000000 s19=00000000 d09=0000000000000000 s20=00000000 s21=00000000 d10=0000000000000000 s22=00000000 s23=00000000 d11=0000000000000000 s24=00000000 s25=00000000 d12=0000000000000000 s26=00000000 s27=00000000 d13=0000000000000000 s28=00000000 s29=00000000 d14=0000000000000000 s30=00000000 s31=00000000 d15=0000000000000000 FPSCR: 00000000 thanks jason.
