Hi,

So we built a Bootloader for the CCG5 based on CCG3PA CC line bootloader as instructed by you, now it seems that the Cypress Config utility is not able to send data to program our device.

Pleases see images and let us know what other hoops we need to jump through

Not sure why

you can just see that the packets are transmitted 5 * 24 + 8 = 128 byte, not as it should be 10 * 24 + 16 = 256 byte for CCG5.

also in the configuration utility build 236, it is clear that the data packets are the same for all the rows, at the same time the build 115 send the data packets corresponding to the rows, but also cut to the size of 5 * 24 + 8.

the only thing that can be done is to prepare a cyacd file for upgrade in 128 row size, and in the bootloader to merge 2 rows to one row.

Summary of resolution:

Custom bootloader had to implement merging 128B rows into 256B.

Successful firmware update was reported.

Hi,

Are you able to read the complete firmware over CC successfully?

(I mean the FW that was programmed over SWD, along with cc-bootloader).

Regards,

Rajath
