question on devices

[schaefer01]

hi,
I was working with the linux bootloader provided by TI but it was delivered in binary, is fragile, and doesn't identify detailed errors.

I am using your code as a basis for a better linux host bootloader, and I am also modifying some of your core to be less fragile and return more information on errors returned by the firmware BSL.

By fragile, I mean that sometimes a sync, if late or repeated, will be responded to by a not-a-header-ack which, to my thinking, is ok and not an error. Your initial sync code just returns w/o reporting what is going on inside, such as timeout.
Rather than identify issues one-by-one that are shades of judgement and interpretation (i.e. you might not agree),
I'm just going to hack away.

Question/issue: I am wondering if I can give you the source when I am done, to do with whatever?

Hi Bob,
I'm glad the project might be of use for you - even though my project is in an initial state.
You are more than welcome to provide feedback, sources (when you are done), pull requests.

Thank you and best regards,
Max

Hi, Max, I’m at the point where everything (the data, the crc) is perfect but the boot fails. I’d like to read back the flash’ed data block in case the problem is the timing on the flash write on the 432 side. I see you haven’t implemented ebh_tx_data_block_32(), so I am going to try to code that. I’ve got a question. ebh_format_package() sends data for rx, do I just replace the send with a receive for tx? thanks, bob s.

I am working with a launchpad first because the lab setup makes it difficult to develop new software or bring the bespoke board back home. I assume the launchpad is using MSP432BSL_1_01_00_00, correct me if I am wrong. Problems: 1. the version per the BSL source is 2 bytes, but the documentation and the handler for the version return 10 bytes. the reason that I believe this is a bug, is the variable that holds the version is declared as a 2 byte array: BSL432_Command_Interpreter.c: const uint8_t BSL432_VersionVendor[2] = {0x00, 0x00}; // TI production build uses case BSL432_TX_BSL_VERSION: { BSL432_CI_sendDataBlock((uint32_t)(&BSL432_VersionVendor), 10); break; } This might be a double-bug in that this is the version vendor and not the version id, which is also a 2 byte variable also, when 10 bytes are returned, they seem to be sending the contents of the next variables declared. 2. my attempts to flash load on the launchpad return no error, but the launchpad does not boot to the program loaded, I print to console the byte blocks and this matches the .txt file loaded. I am guessing at this point the flash might not have loaded, perhaps due to timing between commands. So I am attempting to code the read flash function to read back and compare, i.e. BSL432_TX_DATA_BLOCK On requesting a 256 byte block, the BSL attempts to send 256+1 bytes, the extra byte is not the crc, but seems to be an off-by-one error in the function: BSL432_CI_sendDataBlock statement: BSL432_PI_sendData(bytes + 1); thank you for your consideration. bob s.
