I'm trying to write to the PINSEL2 register, to ensure that it has 0's at bit 2 and 3, but if I try to write to the register, the JTAG connection drops, and it seems as if the MCU enter some other mode, since I can't restore the connection whitout having to do a power cycle. Has anyone experienced this? And how can I write to the PINSEL2 register, whitout having this problem? /Søren

Some bits disable JTAG, be sure to set these to the correctly. -- 42Bastian Schick

Hello Søren,
Not sure what processor you are using but I think you are diabling the JTAG by changing a JTAG line into a GPIO line.
I am using the LC2129 and the usermanual of this processor shows the following:
Table 63: Pin Function Select Register 2 for LPC2119/2129/2194
(PINSEL2 - 0xE002C014)
1:0 Reserved.
2 When 0, pins P1.36:26 are used as GPIO pins.
When 1, P1.31:26 are used as a Debug port. (RTCK)
3 When 0, pins P1.25:16 are used as GPIO pins.
When 1, P1.25:16 are used as a Trace port. (TRACESYNC)
4:5 Reserved. Note: These bits must not be altered at any time.
Changing them may result in an incorrect code execution.
6:31 Reserved.
According to this info you are disabling the JTAG RTCK line.
Hope this helps,
Aalt

Hello Soren, I think your hardware is running fine, probably the behaviour is not what your expecting but that is not caused by a hardware failure. Look in the User Manual of the LPC2132, you can find it on the Philips site. The manual tells: Warning: use read-modify-write operation when accessing PINSEL2 register. Accidental write of 0 to bit 2 and/or bit 3 results in loss of debug and/or trace functionality! Changing of either bit 4 or bit 5 from 1 to 0 may cause an incorrect code execution! The same manual shows in Table 60 that the Reset value of bit 2 isn't 0, the default value is the inverted level that is at P1.26 (RTCK) during Reset. This P1.26 needs to be low during reset if you want to use the JTAG port. This will result in setting bit 2 of PINSEL2. If you clear this bit then it will disable the JTAG port. Regarding your code: I think your line of code isn't doing what you want it to do. PINSEL2 = (PINSEL2 & (0 << 2) & (0 << 3)); You are 'anding' PINSEL2 with 0 because the both (0 << #) items will evalute to 0. If you want to clear a bit then you have to 'AND' with the inverted bitvalue to prevent the changing of the other bits . (I think it should be something like ~(1<<2) Regards Aalt soren_t_hansen wrote: > --- In lpc2000@yahoogroups.com, "Aalt Lokhorst" <lokhorst@s...> wrote: > > Hello Søren, > > > > Not sure what processor you are using but I think you are diabling > the JTAG by changing a JTAG line into a GPIO line. > > > > I am using the LC2129 and the usermanual of this processor shows the > following: > > > > Table 63: Pin Function Select Register 2 for LPC2119/2129/2194 > > (PINSEL2 - 0xE002C014) > > > > 1:0 Reserved. > > > > 2 When 0, pins P1.36:26 are used as GPIO pins. > > When 1, P1.31:26 are used as a Debug port.

PINSEL2 = (PINSEL2 & (0 << 2) & (0 << 3)); According to this, you're clearing PINSEL2 altogether.

I can't use ISP because my hardware does not allow to do it. And one more thing: user manual says that one can't write 1s at specified position to PINSEL2 but i write 0 to it and JTAG crashes. please help Adam

Hi! If you write PINSEL2 bit 2 to zero, this disable the debug resource on the LPC microcontroller. So, if you need to debug yor firmware, this bit PINSEL2:2 must be 1, to ensure the P1.31-26 are enabled as debug port. I hope this help! Regards! German ----- Original Message -----

When you say that your hardware doesn't support ISP, I am guessing you just don't have the UART setup to communicate with the PC. Can you still pull pin P0.14 low during reset to have the chip enter bootloader mode anyway? If so, your code that disabled the JTAG interface won't get to run (the Philips ISP bootloader will run instead) and then you can connect through the JTAG interface and reprogram the chip. Did you also write 0 to bit 2? If so, this would switch the JTAG pins into GPIO mode instead of debug mode. --- upanie1 <upanie@...> wrote: > OK, but how to this if i can't load new program - > JTAG doesn't want to > work.

Thanks. I used P0.14 to get rid of my program and reprogramed it via JTAG. Smart idea. Thanks again. Adam Stanley Frederickson wrote:
