ARM Cortex / Re: LPC1112 Bootloader - shared serial port
« Last post by thiagorod on April 10, 2018, 12:32:34 pm »
Thanks for you reply Andy.

I agree with that, I´ve seen some ideas to split the UART, using resistors, diodes, but this is really not recommended, right?

Regards,

I guess an errant Windows update broke something, but perhaps they have now fixed it. Thanks for posting an update.

Yes, you can. Simply avoid erasing after programming the first hex file.

UART/RS232 is point-to-point and isn't designed for multiple devices to be attached to it. Use jumpers or tri-state outputs instead.

Hmmm... downloads seem slow for me as well, but using Chrome the downloads are successful. We will keep monitoring it to see if there is a pattern.

General Discussion / Slow download which bugs out Chrome
« Last post by buzmeg on April 05, 2018, 06:38:14 pm »
When I attempt to download the latest FlashMagic.exe (version 11), I am barely seeing 30KB/sec download speeds.  I also get network drops which cause Chrome to throw a hissy fit.

If I download the OS X version with Safari, I see a checksum error.

I have also gotten Internal Server Errors.

Is something wrong with the servers or the images on them?  Is there an alternate server from which to download this or a slightly older version?

Thanks.

Hi Andy!

The problem is gone! I mean... It is still there but is not showing up now.
I don't think the issue has anything to do with the windows updates, yet, if you still want the list of updates I can send them to you.
I have the Windows fully updated with all available updates as of today, both critical and optional.

Without changing anything else on my PC except my system date/time I get:
date <= 24 March ---> OK
25 March <= date <= 31 March ---> Not authorized issue
date >= 1 April ---> OK

I have tested this on several Windows 7 PCs with the same result.
Odd!

General / Can I flash two hex files to LPC11u3x using flash magic
« Last post by Thanos on April 03, 2018, 11:35:46 pm »
Hi all,

I have two hex files, one which is iap code and other is my application code.
The iap resides at 0h location and application starts from 4000h location .
Now I want to flash these two hex files to the device using flash magic, how can I achieve this.

First of all,  can I program two hex files at different location on the same device using flash magic

ARM Cortex / LPC1112 Bootloader - shared serial port
« Last post by thiagorod on April 03, 2018, 12:29:28 pm »
Hello,

Is it still possible to program the LPC1112 via serial port (using the bootloader) even if the serial port is being used by a different IC (serial-USB converter for instance) ? Or is it necessary to add resistors to one of the branches ?

Regards,

Can you please give me a list of all updates you have on your PC - should be able to see them in Control Panel -> Uninstall Applications. What was installed between the last time it ran OK and March 26th?

Also what service pack level are you at with Windows 7?

Meanwhile version 10.90 is available that does not have this problem.

Thanks, Andy
