NG mode, esp firmware and hosted driver can’t be compatible with older versions

Hi @kapilkedawat. HI @Shreyas0-7. When I upgrade separately, only esp firmware or hosted driver, the esp32 unable to communicate host. How should I maintain my old product

@lwj850533527 suggest to rebase your code.. also may we ask what kind of changes do you have in host/firmware?

[lwj850533527]

Hi @kapilkedawat. I upgrade separately only esp firmware, but hosted driver didn't upgrade. I think the issue because of the commit https://github.com/espressif/esp-hosted/commit/2e6603687a2dab44e1ef4a6fdf615b61b2b4bd3a

[kapilkedawat]

Hi @lwj850533527, Please don't only upgrade firmware.. host and firmware always supposed to be upgraded in sync..

[lwj850533527]

Hi @kapilkedawat. At present, there is no upgrade channel for firmware.

How should I maintain my old product

Esp firmware and hosted driver can’t be compatible with older versions.

Hey @lwj850533527 please find the below patch hosted_ota.zip This patch has changes for fw too, please flash these changes for firmware once Later on ota can be done by using host using this command cd {home}/esp_hosted/esp_hosted_ng/host/ ./rpi_init.sh transport ota_file=/path/to/ota_file" where transport can be spi or sdio Also you need to follow this guide inorder to use rpi_init on your device https://github.com/espressif/esp-hosted/blob/master/esp_hosted_ng/docs/setup.md#11-host-software-setup
