Verifying the Contents of a Device

Step 3: If you chose to verify a single device against PC memory, you must now specify the error file. Otherwise, verification errors are indicated with the red LEDs found below each device socket. If you have en- tered an error file previously, it will appear as the default.

Error File:

Step 4: If you are verifying against PC memory, you must select the address range to be used during verification.

PC memory base address: all

The default for the base address prompt, all, causes the valid address ranges defined for the current device type to be used as the blocks of PC memory for verification. The valid address ranges also determine the locations in the device from which the data bytes are read.

However, if you want to verify the device from a block of PC memory other than the default, enter an address to specify the start address of the block. Then enter the size of the block at the next prompt.

Size (in bytes): 0000h

When specifying values other than the default, you must also define the device base address, where the verification should begin, at the following prompt.

Device base address:

The default for this prompt is the value entered for the PC memory base address prompt. If you want to read from a different device lo- cation, enter the new address here.

After you have entered all the parameters correctly (or simply chosen all at the PC memory base address prompt), the Gang programmer conducts a device test. If the device you have chosen fails (or any sockets are empty) the pro- grammer beeps and turns on the LED below the failed device. Also, an error message prompts you about the device failure:

Device test failed, continue? (y/n)

At this time, you should try to re-insert the failed device and start verifying its contents again.

It is possible that a defective deviceÐa device with bent pins or a device that has been incorrectly insertedÐwill affect all of the devices on the gang pro- grammer. If this is the case, the following error message is displayed:

unable to communicate with TMS370 device ± Retry, Abort

You should inspect all of the devices for misalignment or bent pins. You may have to remove devices until the bad device is found.
