OpenOCD JTAG / Re: 5.9 and 5.10 firmware still no OpenOCD?
I have the same problem as described by others:
 
Code: [Select]
$ src/openocd tcl/interface/buspirate.cfg
Open On-Chip Debugger 0.5.0-dev-00807-gdec80e1 (2011-03-24-09:39)
Licensed under GNU GPL v2
For bug reports, read
	http://openocd.berlios.de/doc/doxygen/bugs.html
Warn : Adapter driver 'buspirate' did not declare which transports it allows; assuming legacy JTAG-only
Info : only one transport option; autoselect 'jtag'
srst_only separate srst_gates_jtag srst_open_drain
trst_and_srst separate srst_gates_jtag trst_push_pull srst_open_drain
adapter_nsrst_delay: 300
jtag_ntrst_delay: 200
RCLK - adaptive
Error: Error reading data
Error: Buspirate error. Is is binary//OpenOCD support enabled?

My firmware version is:
Code: [Select]
HiZ>i
Bus Pirate v3b
Firmware v5.10 (r559)  Bootloader v4.4
DEVID:0x0447 REVID:0x3043 (24FJ64GA002 B5)
http://dangerousprototypes.com

So I downloaded the posted firmware and got this error:
Code: [Select]
./pirate-loader_lnx --dev=/dev/ttyUSB0 --hex=busPirate.production.hex 
+++++++++++++++++++++++++++++++++++++++++++
+ Pirate-Loader for BP with Bootloader v4 +
+++++++++++++++++++++++++++++++++++++++++++

Parsing HEX file [busPirate.production.hex]
Checksum does not match, line 4
Could not load HEX file, result=-1

Is there anything wrong with my firmware upgrade process?
Thanks,

Roman

Thanks Anton, I think I finally got it right:

Bus Pirate Support / Re: 24AA I2C EEPROM Bus Pirate Demo
Thank you very much, it is getting better but I still have some problems. I can write and consequently read what was written as follows:

Writing 0xA0
Code: [Select]
I2C>[0xa0 0x00 0x0a]
I2C START BIT
WRITE: 0xA0 ACK 
WRITE: 0x00 ACK 
WRITE: 0x0A ACK 
I2C STOP BIT

I2C>[0xa1 r]
I2C START BIT
WRITE: 0xA1 ACK 
READ: 0x0A 
NACK
I2C STOP BIT

Writing 0xA2
Code: [Select]
I2C>[0xa2 0x00 0x0b]
I2C START BIT
WRITE: 0xA2 ACK 
WRITE: 0x00 ACK 
WRITE: 0x0B ACK 
I2C STOP BIT

I2C>[0xa3 r]
I2C START BIT
WRITE: 0xA3 ACK 
READ: 0x0B 
NACK
I2C STOP BIT

Now I would like to read again 0xA0

Code: [Select]
I2C>[0xa0 0x00]
I2C START BIT
WRITE: 0xA0 ACK 
WRITE: 0x00 ACK 
I2C STOP BIT

I2C>[0xa1 r]
I2C START BIT
WRITE: 0xA1 ACK 
READ: 0x0B 
NACK
I2C STOP BIT

It is still not working. I must still be doing something wrong. Here is the output:

Bus Pirate Support / 24AA I2C EEPROM Bus Pirate Demo
I can succesfully run 25AA SPI EEPROM demo but I have a problem with 24AA I2C EEPROM demo from
http://dangerousprototypes.com/docs/3EE ... orer_board
Is there anything wrong with the way I use Bus Pirate for I2C?
Thanks,

Roman
