* target: slow targets could cause GDB to time outGary Carlson2010-05-191-1/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This second half of the patch is proposed to clean up some GDB keep alive issues on arm7_9 targets that start up with very slow clocks. If an attempt is made to write to key registers on the processor with a slow jtag speed, GDB timeout warnings appear on the console (at least mine) when "reset halt" or "reset init" commands are issued from the gdb client: *** BEFORE PATCH *** (gdb) monitor reset init fast memory access is disabled 2 kHz keep_alive() was not invoked in the 1000ms timelimit.

I only did this however for non-fast write memory accesses. I don't think most people would be using fast memory accesses to write to memory when the jtag and system clocks are slow anyway. If you disagree with my feeling, think there is a more elegant way to handle the problem, or think the patch will cause other unforeseen problems with other targets, let me know. As you can see below, the patch does eliminate the problem on my development station and I suspect that it will benefit others. *** AFTER PATCH *** (gdb) monitor reset init fast memory access is disabled 2 kHz JTAG tap: at91sam9g20.cpu tap/device found: 0x0792603f (mfg: 0x01f, part: 0x7926, ver: 0x0) target state: halted target halted in ARM state due to breakpoint, current mode: Supervisor cpsr: 0x000000d3 pc: 0x00000000 MMU: disabled, D-Cache: disabled, I-Cache: disabled RCLK - adaptive dcc downloads are enabled fast memory access is enabled NAND flash device 'NAND 256MiB 3,3V 8-bit' found (gdb) Gary Carlson Gary Carlson, MSEE Principal Engineer Carlson-Minot Inc.

* flash: stop caching protection stateØyvind Harboe2010-05-051-13/+0
| | | | | | | | | | | | | | There are a million reasons why cached protection state might be stale: power cycling of target, reset, code executing on the target, etc. The "flash protect_check" command is now gone. This is *always* executed when running a "flash info". As a bonus for more a more robust approach, lots of code could be deleted. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>

* xscale: add support for length arg to wp commandMike Dunn2010-04-241-8/+51
| | | | | | | | | | | | | | | | | | | | | | | This patch adds support for the length argument to the xscale implementation of the wp command. Per discussion with David, the length argument specifies the range of addresses over which a memory access should generate a debug exception. This patch utilizes the "mask" feature of the xscale debug hardware to implement the correct functionality of the length argument. Some limitations imposed by the hardware are: - The length must be a power of two, with a minumum of 4. - Two data breakpoint registers are available, allowing for two watchpoints. However, if the length of a watchpoint is greater than four, both registers are used (the second for a mask value), limiting the number of watchpoints to one. This patch also removes a useless call to xscale_get_reg(dbcon) in xscale_set_watchpoint() (value had already been read from the register cache, and the same previously read value is then modified and written back). I have been using and testing this patch for a couple days. Questions, corrections, criticisms of course gratefully received.
* xscale: fix analyze_trace for trace data collected in wrap modeMike Dunn2010-04-152-216/+243
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes the xscale_analyze_trace() function. This function was defective for a trace collected in 'fill' mode (hiccups with repeated instructions) and completely broken when buffer overflowed in 'wrap' mode. The reason for the latter case is that the checkpoint registers were interpreted incorrectly when two checkpoints are present in the trace (which will be true in 'wrap' mode once the buffer fills). In this case, checkpoint1 register will contain the older entry, and checkpoint0 the newer. The original code assumed the opposite. I eventually gave up trying to understand all the logic of the function, and rewrote it. I think it's much cleaner and understandable now. I have been using and testing this for a few weeks now. I'm confident it hasn't regressed in any way. Also added capability to handle (as best as possible) the case where an instruction can not be read from the loaded trace image; e.g., partial image. This was a 'TODO' comment in the original xscale_analyze_trace(). Outside of xcsale_analyze_trace(), these (related) changes were made: - Remove pc_ok and current_pc elements from struct xscale_trace. These elements and associated logic are useless clutter because the very first entry placed in the trace buffer is always an indirect jump to the address at which execution resumed. This type of trace entry includes the literal address in the trace buffer, so the initial address of the trace is immediately determined from the trace buffer contents and does not need to be recorded when trace is enabled. - Added num_checkpoints to struct xscale_trace_data, which is necessary in order to correctly interpret the checkpoint register contents. - In xscale_read_trace() - Fix potential array out-of-bounds condition. - Eliminate partial address entries when parsing trace (can occur in wrap mode). - Count and record number of checkpoints in trace. - Added small, inlined utility function xscale_display_instruction() to help make the code more concise and clear. TODO: - Save processor state (arm or thumb) in struct xscale_trace when trace is enabled so that trace can be analyzed correctly (currently assumes arm mode). - Add element to struct xscale_trace that records (when trace is enabled) whether vector table is relocated high (to 0xffff0000) or not, so that a branch to an exception vector is traced correctly (curently assumes vectors at 0x0).
* cortex-a8: more MMU supportAnton Fedotov2010-04-142-98/+321
| | | | | | | | | | | | | | | | | | | + virt2phys() can now convert virtual address to real + read_memory() and write_memory() are renamed to read_phys_memory() and write_phys_memory() + new read_memory() and write_memory() try to resolve real address if mmu is enambled than perform real address reading/writing + if address is bellow 0xc000000 than TTB0 is used for page table dereference, if above - than TTB1. Linux style of user/kernel address separation + if above fails (i.e address is unspecified) than mode is checked whether it is Supervisor (than TTB1) or User (than TTB0) - Software breakpoints doesn't work. You should invoke "gdb_breakpoint_override hard" before you start debugging + cortex_a8_mmu(), cortex_a8_enable_mmu_caches(), cortex_a8_disable_mmu_caches() are implemented Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
