Those are very interesting. First thing to note is that you're using old deprecated ft2232 driver with 0.7.0 and the new ftdi driver with 0.8.0. There might be some subtle difference in how they work, I guess it might make sense to try ft2232 on 0.8.0 too and compare the results. Second important thing is where the problems start, on a good run: Debug: 231 668 arm_adi_v5.c:1227 dap_find_ap(): Found APB-AP at AP index: 1 (IDR=0x24770002) Debug: 232 670 arm_adi_v5.c:1227 dap_find_ap(): Found AHB-AP at AP index: 0 (IDR=0x44770001) Debug: 233 685 cortex_a.c:2466 cortex_a8_examine_first(): cpuid = 0x561f5811 Debug: 234 685 cortex_a.c:2467 cortex_a8_examine_first(): ctypr = 0x8003c003 Debug: 235 685 cortex_a.c:2468 cortex_a8_examine_first(): ttypr = 0x00000000 Debug: 236 685 cortex_a.c:2469 cortex_a8_examine_first(): didr = 0x15140011 Info : 237 685 arm_dpm.c:986 arm_dpm_setup(): armada370.cpu: hardware has 6 breakpoints, 2 watchpoints Debug: 238 685 cortex_a.c:707 cortex_a8_bpwp_disable(): A8: bpwp disable, cr c2301140 Debug: 239 687 cortex_a.c:707 cortex_a8_bpwp_disable(): A8: bpwp disable, cr c2301144 Debug: 240 689 cortex_a.c:707 cortex_a8_bpwp_disable(): A8: bpwp disable, cr c2301148 Debug: 241 691 cortex_a.c:707 cortex_a8_bpwp_disable(): A8: bpwp disable, cr c230114c Debug: 242 693 cortex_a.c:707 cortex_a8_bpwp_disable(): A8: bpwp disable, cr c2301150 Debug: 243 696 cortex_a.c:707 cortex_a8_bpwp_disable(): A8: bpwp disable, cr c2301154 Debug: 244 698 cortex_a.c:707 cortex_a8_bpwp_disable(): A8: bpwp disable, cr c23011c0 Debug: 245 700 cortex_a.c:707 cortex_a8_bpwp_disable(): A8: bpwp disable, cr c23011c4 Debug: 246 702 cortex_a.c:2493 cortex_a8_examine_first(): Configured 6 hw breakpoints And on a bad: Debug: 250 433 arm_adi_v5.c:868 ahbap_debugport_init(): MEM_AP Packed Transfers: enabled Debug: 251 435 arm_adi_v5.c:930 dap_find_ap(): Found APB-AP at AP index: 1 (IDR=0x24770002) Debug: 252 436 arm_adi_v5.c:930 dap_find_ap(): Found AHB-AP at AP index: 0 (IDR=0x44770001) Debug: 253 444 cortex_a.c:2439 cortex_a8_examine_first(): cpuid = 0x561f5811 Debug: 254 444 cortex_a.c:2440 cortex_a8_examine_first(): ctypr = 0x8003c003 Debug: 255 444 cortex_a.c:2441 cortex_a8_examine_first(): ttypr = 0x00000000 Debug: 256 444 cortex_a.c:2442 cortex_a8_examine_first(): didr = 0x15140011 Info : 257 444 arm_dpm.c:986 arm_dpm_setup(): armada370.cpu: hardware has 6 breakpoints, 2 watchpoints Debug: 258 444 cortex_a.c:702 cortex_a8_bpwp_disable(): A8: bpwp disable, cr c2301140 Debug: 259 445 adi_v5_jtag.c:271 jtagdp_transaction_endcheck(): jtag-dp: CTRL/STAT error, 0xf0000021 Debug: 260 445 adi_v5_jtag.c:291 jtagdp_transaction_endcheck(): MEM-AP Cached values: ap_bank 0x10, ap_csw 0xa2000002, ap_tar 0xc2301140 Error: 261 445 adi_v5_jtag.c:298 jtagdp_transaction_endcheck(): JTAG-DP STICKY ERROR Debug: 262 446 adi_v5_jtag.c:315 jtagdp_transaction_endcheck(): jtag-dp: CTRL/STAT 0xf0000001 Error: 263 447 adi_v5_jtag.c:331 jtagdp_transaction_endcheck(): MEM_AP_CSW 0x80000042, MEM_AP_TAR 0xc2301140 ...
