Last wood debug mode5/16/2023 ![]() ![]() Under normal circumstances, you will see notifications of major critical errors on your site. When you encounter an error on your WordPress website, this is a small part of the debug process in action – the end point. ![]() In lots of cases, you already see a version of debugging in action. ![]() First off, let’s offer you more insight into what the mode does. In this post, we’re going to show you everything you need to know about the WordPress debug mode. Though, once the debug mode gives you a helping hand, the repair process is often straightforward. Some debug messages will give you a pointer. In this sort of situation, the WordPress debug mode is a lifesaver.ĭebugging is a way to find out why a ‘bug’ is causing havoc, although you’ll also have to figure out how to fix it. What’s more, it could be that you have no idea how it got there or what you can do to fix it. I will try to monitor closer to the CC2510 which is on a separate pcb connected by about 15cm of flat cable.Despite how stable WordPress is as a platform, you will encounter an error at some point. I'm monitoring at the outputs of a 74HC05 which drives the DC and DD lines. Our clock timings are very slow in relation to the minimum widths (several microsec).įrom all you say, my view is that the most likely problem is noise on the clock line. ![]() I have tried however with a delay of tens of microsec - no success. I started using GET CHIP ID at the suggestion of a TI FAE and thought we were getting somewhere when it seemed to be close to the expected response.Ĭan I pick up your question about trying to read the return byte too soon? I did wonder about this, although I see nothing in the documentation about the need to insert a delay. We have always seen FF in reply to the GET DEBUG STATUS command and to other commands I have tried. So you say that we should see 8104 (as per the documentation) not the 8217 which we are seeing consistently. Yes we have the Debug & Programming Interface Spec, though it doesn't give much more detail than is in the datasheet. Also, if you toggle the debug clock (DC) signal unintentionally by the external host, the CC2510 and the external host will lose bit synchronization, and further communication will probably fail since it is strictly byte-oriented.Īre you able to read chip status (READ_STATUS command is 0x34) and get a sensible value (see table 47 in the data sheet - I think you should see a status byte of 0x22 or something close to that. If the chip is on a board with significant electromagnetic interference, unintentional noise on the RESETn line could of course bring it out of debug mode. So it shouldn't be a problem to wait as long as you like before you start feeding it any debug commands (e.g. long signal traces) on any of the debug interface signals you might have to reduce bit rate according to compensate for the increased transition time. The signal voltages on DD / DC lines should be the same level as the chip's VDD power, but you probably have ensured that.Īfter you've done a "enter-debug-mode" sequence (=exactly 2 rising transitions on DC line while RESETn has been asserted and then released, as you described) the chip should remain in debug mode until you manually do a reset. Since your first byte is very close to the expected value, could it be related to bit timing or synchronization of DC / DD lines? Could it be that you attempt to read the return (ouput) byte too soon? Have you verified the bit rate is within the spec timing-wise, with an oscilloscope or logic analyzer? If you have capacitive load (e.g. Have you looked at the document "CC1110/CC2510/CC2430 Debug and Programming Interface Specification" (swra124a)? It can be helpful, illustrating the expected waveforms. You say you read 0x82 as the first byte, which is not a valid value - this could indicate there is somehow an error in your device communication. Hence, the expected output bytes are 0x81 (=CC2510) and 0x04 (=rev E). The GET_CHIP_ID debug command should return two bytes: the PARTNUM and VERSION register values. ![]()
