I've written a bootloader that you can arm the
file for download and when the program see the S-Record message come for the
board it starts the download. I set BSP_BOOTLOADER_DELAY to 2 seconds for
all my boards and don't have a problem. Below is a link to the
program.
It needs a little work still, namely the comm port
can not be selected manually. To pick the comm port you have to click on
the "Auto Detect" button, which it will not detect anything. Then pick you
comm port from the list.

From: bmbmz123 [mailto:b...@mer.co.il] Sent: Monday, March 15, 2004 8:55 AM To: m...@yahoogroups.com Subject: [motoroladsp] SDK Serial Bootloader I've just started using the Bootloader. I'm using the OLD version 1.1, as I have CW ver 4.1 (and upgrading is not an option, espedially at the end of a project). Chip used: 826 (and also 827 at a later stage, after I figure out this "simpler boot chip"). I'm not sure if I'm using it correctly. I want to be able to download updated versions of the sw, in the field, with a PC/Laptop. I downloaded the boot using JTAG. I programed the S-file via SCI. Up to now, OK. But, when I use the sw, after reset of power up the sw waits for 30 seconds before running!! - according to default BSP_BOOTLOADER_DELAY value. This is not acceptable. So, I changed BSP_BOOTLOADER_DELAY to 5 seconds. But, if I want to download a new version, I must be Super Fast to be able to start download before the application starts!! So, what is the answer for Field Upgrade SW?? Will I need to write the boot sw myself?? 10x Boaz _____________________________________ Note: If you do a simple "reply" with your email client, only the author of this message will receive your answer.
